Answer:

Step-by-step explanation:
5 ft 3 inches = 63 inches
3 ft 10 inches = 46 inches
63-14 = 17 inches
Answer:
17 inches
1 foot 5 inches
Step-by-step explanation:
1 foot = 12 imches
First we multiply :)
5 x 12 = 60
3 x 12 = 36
Now we add on the already there inches :)
60 + 3 = 63
36 + 10 = 46
Finally we subtract :)
63 - 46 = 17
17/12 = 1 foot 5 inches :)

factorise:-
(a+b)³ - (a-b)³
[tex](a+b)^3 -(a-b)^3\\\\=(a+b-a+b)[(a+b)^2 + (a+b)(a-b) +(a-b)^2]\\\\=2b(a^2+b^2+2ab+a^2-b^2 +a^2 +b^2 -2ab)\\\\=2b(3a^2+b^2)[/tex]
Answer:
Step-by-step explanation:
(a + b)³ - (a - b)³ = a³ + 3a²b + 3ab² + b³ - [a³ - 3a²b + 3ab² -b³]
= a³ + 3a²b + 3ab² + b³ - a³ + 3a²b - 3ab² + b³
= a³ - a³ + 3a²b + 3a²b + 3ab² - 3ab² + b³ + b³
Here, the underlined terms will be cancelled.
= 6a²b + 2b³
= 2 * 3 *a²*b + 2*b³
= 2b* (3a² + b²)
Based on your value of x in question #1, what is the value for ∠EHF
1) 132 degrees
2) 96 degrees
3) 180 degrees
4) 90 degrees
Answer:
∠EHF = 132°
Step-by-step explanation:
Both angles lie on a straight line.
=====================
∠EHF + ∠FHG = 180°2(x) + 48° = 180°2(x) = 180° - 48°2(x) = 132°x = 66°Then ∠EHF :
2(x)2(66)132°Angles are supplementary hence their sum is 180°
So
2x+48=1802x=180-482x=132x=66So
<EHF=2(66)=132°

Resolve into factors.
Answer:
[tex]\fbox{(a+b) and (a+b+1) are the factors}[/tex]
Step-by-step explanation:
Given equation = a² + 2ab + b² + a + b
Let's factorise,
We know that,
[tex]{(a + b)}^{2} = {a}^{2} + 2ab + {b}^{2} [/tex]
Substituting the above factor in given equation,
[tex] {a}^{2} + 2ab + {b}^{2} + a + b = {(a + b)}^{2} + a + b \\ Taking \: (a+b) \: common \: in \: RHS \\ {a}^{2} + 2ab + {b}^{2} + a + b = (a + b)(a + b + 1) \\[/tex]

Which equations can be used to find the lengths of the legs of the triangle? Select three options.
0.5(x)(x + 2) = 24
x(x + 2) = 24
x2 + 2x – 24 = 0
x2 + 2x – 48 = 0
x2 + (x + 2)2 = 100
The equations that can be used to find the lengths of the legs of the triangle are x^2 + (x+2)^2 = 100, x^2 + 2x - 48 = 0 and 0.5x(x+2) = 24
Pythaogram theoremAccording to the theorem, the square of the hypotenuse is equal to the sum of the square of other two sides.
From the diagram
hypotenuse = 10ft
Other sides are x and (x+2)ft
According to the theorem:
10^2 = x^2 + (x+2)^2
x^2 + (x+2)^2 = 100
Expand
x^2 + x^2 + 4x + 4 = 100
2x^2 + 4x - 96 = 0
x^2 + 2x - 48 = 0
Divide through by 2
0.5x^2 +x - 24 = 0
0.5x(x+2) = 24
Hence the equations that can be used to find the lengths of the legs of the triangle are x^2 + (x+2)^2 = 100, x^2 + 2x - 48 = 0 and 0.5x(x+2) = 24

Step-by-step explanation:
A)1 cm:8 inch
(1×6)cm:(8×6)inch
Thus, if the height is 48 inch, the scale in cm is 6 cm
B)Normal linear form
The length=4cm

Is –6 − 65 positive or negative?
Answer:
It is negative.
Step-by-step explanation:
-6 - 65 is -71
Hope that helps!
Answer:
negative
Step-by-step explanation:
The equation -6 - 65 equals -71 because 65 is a positive number and -6 is not which means it must keep going negative because a negative plus a positive goes negative.

Solve for x in the triangle. Round your answer to the nearest tenth. (Please help)
Answer:
x = 6.5
Step-by-step explanation:
Since this is a right triangle we can use trig functions
cos theta = adjacent side / hypotenuse
cos 23 = 6/x
x cos 23 / 6
x = 6 /cos 23
x=6.51816
Rounding to the nearest tenth

[tex]\sqrt{5} \sqrt{10} +\sqrt{5} \sqrt{2} < -- Distribute[/tex]
An equation is in its simpliest form when you eliminate as many square roots as possible. Here are some rules:
1.) You cannot combine numbers through addition or subtraction if they are under square roots. However, you can combine numbers through multiplication or division if they are under square roots.
2.) You cannot take the square root of a number if the answer is not a whole number (unless the problem says you can). However, you can solve the square root if the number can be simplfied into a "rootable?" number. In other words, the number under a square root can be divided into a number that can have its square root taken.
The first part...
[tex]\sqrt{5} \sqrt{10} = \sqrt{5} * \sqrt{10} < --Multiply[/tex]
[tex]\sqrt{5} * \sqrt{10} =\sqrt{50}[/tex]
[tex]\sqrt{50} = \sqrt{25} *\sqrt{2} < --Separate[/tex]
[tex]\sqrt{25} = 5 < --Solve[/tex]
[tex]\sqrt{50} = 5 *\sqrt{2} < -- Substitute[/tex]
[tex]5*\sqrt{2} =5\sqrt{2} < --Rewrite[/tex]
The second part...
[tex]\sqrt{5} \sqrt{2} =\sqrt{5} * \sqrt{2} < -- Multiply[/tex]
[tex]\sqrt{5} *\sqrt{2} = \sqrt{10}[/tex]
Combine both parts...

i need help finding our the perimeter
Answer:
11x + 10y - 2w
Step-by-step explanation:
Hello!
To solve for the perimeter, we add up the like terms.
What are like terms?
Like terms are terms with the same variable and degree. 4x and 5y are NOT like terms because the variable is not the same. However, 4x and 3x are like terms, as adding them gives us 7x.
4x and 4x² are not like terms, because the degree of 4x is 1 (degree means the largest exponent), but the degree of 4x² is 2.
Solve for Perimeter:
Combine the like terms by adding them up.
Perimeter = (8x - 4w) + (3y + 2w) + (3x + 7y)P = 8x - 4w + 3y + 2w + 3x + 7yP = 8x + 3x + 3y + 7y - 4w + 2wP = 11x + 10y - 2wThe perimeter is 11x + 10y - 2w
