What methods do you know that can be used to solve a quadratic equation?
Answers
Answer: If the quadratic equation has real, rational solutions, the quickest way to solve it is often to factorise into the form (px + q)(mx + n), where m, n, p and q are integers. This is especially true where the coefficient of x2 is 1.

Answer: V = πr 2 h
Step-by-step explanation:
To calculate the volume of a cylinder, you must know its height and the radius of the circular base (the distance from the center of the circle to its edge) at the top and bottom. The formula is V = πr 2 h, where V is the Volume, r is the radius of the circular base, h is the height, and π is the constant pi.

How do you solve 4 over 5 times 3.75
Answers
Answer:
3
Step-by-step explanation:
First of all simplify 4/5 to .8
Then Multiply: .8*3.75=3
9514 1404 393
Answer:
4/5×3.75 = 3
Step-by-step explanation:
There are many solution strategies available. Among them are ...
use a calculator to find 4/5×3.75 = 3convert the numbers to decimal and multiply by hand 0.8×3.75 = 3.000compute 2(2×3.75)/5 = 2(7.5)/5 = 15/5 = 3 in your headconvert 3.75 to an improper fraction and multiply (4/5)(15/4)=15/5=3__
Additional comment
The mental arithmetic involved in adding a number to itself (doubling a number) is usually pretty easy. This means it is relatively easy to multiply by powers of 2, such as 4, 8, or 16. The second strategy listed above can be done in your head as ...
8/10×3.75 = 2×(2×(2×3.75))/10 = 2×(2×7.5)/10 = 2×15/10 = 30/10 = 3
The same product can be found as ...
8/10×3.75 = 8×(3.75/10) = 8×0.375 = 8×(3/8) = 3
In all cases, it is helpful to know your times tables, decimal equivalents of common fractions, and a few shortcut strategies for mental arithmetic. These are not difficult, but they do require you put some effort into memorizing them.
What is the slope of the line that contains these points?

Answer:
8
Step-by-step explanation:
Let,

x2 = 1
y1 = 18
y2 = 26
Formula : -
Slope = ( y2 - y1 ) / ( x2 - x1 )
Slope = ( 26 - 18 ) / ( 1 - 0 )
= 8 / 1
Slope = 8

Answers
Answer:
Answer to the first part: 8a³b + 4ab
Step-by-step explanation:
Perimeter = distance around the three sides
P = 6a³b + 2a³b + 4ab
P = (6a³b + 2a³b) + 4ab add like terms
P = 8a³b +4ab Simply
The value of the perimeter and area of the triangle are,
20.52 cm² and 28.68 cm
What is mean by Triangle?A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.
Now, By Using Pythagoras theorem to find the base of the triangle as;
a² = 6² - 3²
a ² = 27
a = √27
And, b² = 9² - 3²
b² = 72
b = √72
Hence, Base = √27 + √72
= 13.68
So, We get;
Area = 0.5 x 13.68 x 3
Area = 20.52 cm²
And, The value of perimeter is,
Perimeter = 9 + 6 + 13.68
= 28.68
Thus, The value of the perimeter and area of the triangle are,
20.52 cm² and 28.68 cm

On this, I agree with myself. The solution is straightforward. Simply click them in the sequence listed, beginning with the first and ending with the last. Wow, what sleuthing I did. I realize it's not much, but I was perplexed by this as well, so you could be as well. So here we go with the actual answer. To tackle these sorts of issues, you must employ a technique known as PEMDAS, which stands for.
Parenthisis
Exponent
Multiply
Divide
Add Subtract
I realize I spelt the first one incorrectly, but it's 2 a.m. and I'm doing homework for you. Now we must consider whether or not this has any parenthesis. This particular issue does not. Now we must determine whether or not this issue has exponents, which it does. As mentioned in the response box on the lesson's main page. So we have to consider that (spelled incorrectly, but who cares, it's math class)Now we multiply by a power of ten, so the divisor is a whole number. The following step is to divide by calculating how many times 25 equals 105. I realize it was stolen from the question, but whatever. So there was the explanation; I realize I didn't answer the entire problem, but I didn't have to; it wasn't in the cards.

Answer:
( i ) ∠AOB = 72
( ii ) ∠BOC = 67
( iii ) ∠COD = 134
( iv ) ∠AOD = 87
Step-by-step explanation:
Sum of angles in a circle is 360,
a + b + c + x = 360
72 + 67 + 134 + x = 360
273 + x = 360
x = 360 - 273
x = 87
∠AOB = a = 72
∠BOC = b = 67
∠COD = c = 134
∠AOD = x = 87
Step-by-step explanation:
From the diagram,
AOB = a= 72
BOC = b = 67
COD= c = 134
&
AOD+AOB + BOC+ COD= 360 [Angle ofcomplete turn]
or,AOD + 72+67+134= 360
or,AOD +273=360
or AOD= 360-273=87degree

Answers
The solution to the algebraic equation, −0.4x − 3.1 = 5.9, is: x = -22.5
Given the algebraic equation, −0.4x−3.1 = 5.9, to solve for x, follow the steps below:
−0.4x − 3.1 = 5.9
Add 3.1 to both sides−0.4x − 3.1 + 3.1 = 5.9 + 3.1
-0.4x = 9
Divide both sides by -0.4-0.4x/-0.4 = 9/-0.4
x = -22.5
Therefore, the solution to the algebraic equation, −0.4x − 3.1 = 5.9, is: x = -22.5
