The length of a rectangle is the sum of the width and one. The area direct angle 72 units. What’s the length, in units, of the rectangle
Answer:
The length of the rectangle is of 9 units.
Step-by-step explanation:
Solving a quadratic equation:
Given a second order polynomial expressed by the following equation:
[tex]ax^{2} + bx + c, a\neq0[/tex].
This polynomial has roots [tex]x_{1}, x_{2}[/tex] such that [tex]ax^{2} + bx + c = a(x - x_{1})*(x - x_{2})[/tex], given by the following formulas:
[tex]x_{1} = \frac{-b + \sqrt{\bigtriangleup}}{2*a}[/tex]
[tex]x_{2} = \frac{-b - \sqrt{\bigtriangleup}}{2*a}[/tex]
[tex]\bigtriangleup = b^{2} - 4ac[/tex]
Area of a rectangle:
A rectangle has width [tex]w[/tex] and length [tex]l[/tex]. The area is the multiplication of these measures, that is:
[tex]A = wl[/tex]
The length of a rectangle is the sum of the width and one.
This means that [tex]l = w+1[/tex], or [tex]w = l - 1[/tex]
The area direct angle 72 units. What’s the length, in units, of the rectangle
We want to find the length. So
[tex]wl = 72[/tex]
[tex](l-1)l = 72[/tex]
[tex]l^2 - l - 72 = 0[/tex]
Quadratic equation with [tex]a = 1, b = -1, c = -72[/tex]. So
[tex]\bigtriangleup = (-1)^{2} - 4(1)(-72) = 289[/tex]
[tex]l_{1} = \frac{-(-1) + \sqrt{289}}{2*(1)} = 9[/tex]
[tex]l_{2} = \frac{-(-1) - \sqrt{289}}{2*(1)} = -8[/tex]
Since the length is a positive measure, the length of the rectangle is of 9 units.

Consider the points below.
P(2, 0, 2), Q(−2, 1, 3), R(4, 2, 4)
(a) Find a nonzero vector orthogonal to the plane through the points
P, Q,
and R.
Answer:
a) The nonzero vector orthogonal to the plane through the points P, Q and R is (0, 10, -10).
b) The area of the triangle PQR is [tex]5\sqrt{2}[/tex].
Step-by-step explanation:
The statement is incomplete. The complete question will be presented below:
Consider the points below: P(2, 0, 2), Q(−2, 1, 3), R(4, 2, 4)
(a) Find a nonzero vector orthogonal to the plane through the points
P, Q, and R. (b) Find the area of the triangle PQR.
a) Let [tex]P(x,y,z) = (2,0,2)[/tex], [tex]Q(x,y,z) = (-2,1,3)[/tex] and [tex]R(x,y,z) = (4,2,4)[/tex]. First, we construct vectors PQ and PR by using the following formulas:
[tex]\overrightarrow{PQ} = Q(x,y,z) -P(x,y,z)[/tex] (1)
[tex]\overrightarrow{PQ} = (-2,1,3)-(2,0,2)[/tex]
[tex]\overrightarrow{PQ} = (-4,1,1)[/tex]
[tex]\overrightarrow{PR} = R(x,y,z) -P(x,y,z)[/tex] (2)
[tex]\overrightarrow{PR} = (4,2,4)-(2,0,2)[/tex]
[tex]\overrightarrow{PR} = (2,2,2)[/tex]
Then, we can find the nonzero vector orthogonal to the plane by means of the following cross product:
[tex]\vec S = \overrightarrow{PQ}\,\times\,\overrightarrow{PR}[/tex]
Which can be solved by the following determinant (Law of Sarrus):
[tex]\vec S = \left|\begin{array}{ccc}\hat{i}&\hat{j}&\hat{k}\\-4&1&1\\2&2&2\end{array} \right |[/tex]
[tex]\vec S = (2-2,2+8, -8-2)[/tex]
[tex]\vec S = (0, 10,-10)[/tex]
The nonzero vector orthogonal to the plane through the points P, Q and R is (0, 10, -10).
b) The area of the triangle is determined by the following formula:
[tex]A = \frac{1}{2}\cdot \|\overrightarrow{PQ}\,\times\,\overrightarrow{PR} \|[/tex]
[tex]A = \frac{1}{2}\cdot \|\vec S\|[/tex] (3)
[tex]A = \frac{1}{2}\cdot \sqrt{0^{2}+10^{2}+(-10)^{2}}[/tex]
[tex]A = 5\sqrt{2}[/tex]
The area of the triangle PQR is [tex]5\sqrt{2}[/tex].

help please!! FACTOR IT
Answer:
1. Subtract 18 from both sides to get the equation set to 0:
x2 + 7x - 18 = 0
Now factor. Given the negative sign in front of the 18, you will have (x + ) (x - ) as your factors, with the larger one being positive. Now, which factors of 18 can be combined to get a result of 7? I'll leave that for you.
2- 2.3 Solve : p-7 = 0
Add 7 to both sides of the equation :
p = 7

Trying to factor by splitting the middle term
1.1 Factoring x2-16x+63
The first term is, x2 its coefficient is 1 .
The middle term is, -16x its coefficient is -16 .
The last term, "the constant", is +63
Step-1 : Multiply the coefficient of the first term by the constant 1 • 63 = 63
Step-2 : Find two factors of 63 whose sum equals the coefficient of the middle term, which is -16 .
-63 + -1 = -64
-21 + -3 = -24
-9 + -7 = -16 That's it
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -9 and -7
x2 - 9x - 7x - 63

a. -1
b. 0
c. 1
d. 2
20 points! Please help! And hurry!
Answer:
0 (b)
Step-by-step explanation:
So we're estimating in this one.
we can round -49/100 to -50/100 and 10/21 to 10/20
Then we can get a common denominator
10/20 will become 50/100
so
-50/100 + 50/100 = 0
So your answer is b.
Answer:
B. 0
Step-by-step explanation:
-49/100 + 10/21
They are both about half
Therefore, since one is negative and the other is a positive they would equal about .02 which the closest number out of the 4 answers would be B. 0

a gardener wants to build a rectangular fence for his prize winning roses. the length of the fence should be at least 6 feet and the distance around it should be no more than 18 feet. what are the possible dimensions.
Answer:
i. 6 feet by 3 feet
ii. 7 feet by 2 feet
iii. 8 feet by 1 feet
Step-by-step explanation:
From the given question, we have;
length of the rectangular fence, l = 6 feet
perimeter of the rectangular fence = 18 feet
Let the width of the rectangular fence be represented by w.
So that,
Perimeter of a rectangle= 2(length + width)
18 = 2(6 + w)
18 = 12 + 2w
18 - 12 = 2w
6 = 2w
w = [tex]\frac{6}{2}[/tex]
w = 3
The width of the rectangular fence would be 3 feet when the length is 6 feet.
Thus, the possible dimensions of the rectangular fence are:
i. 6 feet by 3 feet
ii. 7 feet by 2 feet
iii. 8 feet by 1 feet

a) Line: y = 5x -8
Point (1,-3)
b) Line: y = -3x+1

Point(-2,-7)
someone help!!!
Answer:
a) yes
The point ( 1,-3) lie on the given line y = 5x-8
b) No
The point ( -2,-7) does not lie on the given line y = -3 x +1
Step-by-step explanation:
Step(i):-
a) Given line y = 5 x - 8 ...(i)
Point ( 1, -3 )
substitute ( 1,-3 ) in equation (i)
-3 = 5(1) - 8
-3 = 5 -8
-3 = -3
∴ The point ( 1,-3) lie on the given line y = 5x-8
b)
Given line y = -3 x +1 ...(i)
Point ( -2, -7 )
substitute (-2, -7 ) in equation (i)
-7 = -3(-2) +1
-7 ≠ 7
The point ( -2,-7) does not lie on the given line y = -3 x +1

The Multiplication of 7 and 2 results to 14.
What is Multiplication?
The fundamental concept of repeatedly adding the same number is represented by the process of multiplication. The results of multiplying two or more numbers are known as the product of those numbers, and the factors that are multiplied are referred to as the factors. Repeated addition of the same number is made easier by multiplying the numbers.
We have to multiply 9 x 34.
So, we can split the number 34 as (30 + 4) then
First, 9 x 30 = 270
and, 9 x 4 = 36
Now, add the values
9 x 34
= 270 + 36
= 306

B. (8i)- (-8i)= 0
C. 8i + 4 = 4i + 8
D. 8i + 4 = 4 + 8i
Answer:D
Step-by-step explanation:its the same thing but the numbers are flipped, you get the same answer either way.
The statement that illustrates the commutative property of addition is
8i + 4 = 4 + 8i. The correct option is D.
What is the commutative property of addition?The commutative property of addition:
Let a and b are numbers.
a + b = b + a
The change in the position of two numbers in an addition operation does not change the sum.
The commutative property of addition:
Let a and b are numbers.
So, a + b = b + a.
LHS = 8i + 4
= 2 (4i+2)
= 2(2 + 4i)
= 4 + 8i
That means, 8i + 4 = 4 + 8i holds the commutative property of addition.
Therefore, the equation is 8i + 4 = 4 + 8i.
