Answer:
x = 5/13
Step-by-step explanation:
![x+\dfrac{2}{13}=\dfrac{7}{13}\\\\ x+\dfrac{2}{13}-\dfrac{2}{13}=\dfrac{7}{13}-\dfrac{2}{13}\\\\x+0=\dfrac{7-2}{13}\\\\\boxed{x=\dfrac{5}{13}=0.38462}](https://tex.z-dn.net/?f=x%2B%5Cdfrac%7B2%7D%7B13%7D%3D%5Cdfrac%7B7%7D%7B13%7D%5C%5C%5C%5C%20x%2B%5Cdfrac%7B2%7D%7B13%7D-%5Cdfrac%7B2%7D%7B13%7D%3D%5Cdfrac%7B7%7D%7B13%7D-%5Cdfrac%7B2%7D%7B13%7D%5C%5C%5C%5Cx%2B0%3D%5Cdfrac%7B7-2%7D%7B13%7D%5C%5C%5C%5C%5Cboxed%7Bx%3D%5Cdfrac%7B5%7D%7B13%7D%3D0.38462%7D)
Answer:
320 sq in
Step-by-step explanation:
4(1/2*8*16) + (8*8)
= 4(64) + (64)
= 5(64)
= 320
Answer:
y = 1/3
Step-by-step explanation:
<u>Step 1: Factor</u>
9y^2 - 6y + 1 = 0
(3y - 1)(3y - 1) = 0
(3y - 1)^2 = 0
<u>Step 2: Solve for y</u>
3y - 1 + 1 = 0 + 1
3y / 3 = 1 / 3
y = 1/3
Answer: y = 1/3
Answer:
b
Step-by-step explanation:
To find the distance between points, use the distance formula.
Distance formula:
![\sqrt{ (x_{2} - x_{1})^{2} + ( y_{2} - y_{1})^{2} }](https://tex.z-dn.net/?f=%20%5Csqrt%7B%20%28x_%7B2%7D%20-%20%20x_%7B1%7D%29%5E%7B2%7D%20%2B%20%28%20y_%7B2%7D%20-%20%20y_%7B1%7D%29%5E%7B2%7D%20%7D%20)
Plug in your values for
![x_{2}, x_{1}, y_{2}, y_{1}](https://tex.z-dn.net/?f=%20x_%7B2%7D%2C%20%20x_%7B1%7D%2C%20%20y_%7B2%7D%2C%20%20y_%7B1%7D)
using (-8, -7) and (8, -4) and solve.
![\sqrt{(8 - (-8))^{2}+(-4 - (-7))^{2}}](https://tex.z-dn.net/?f=%20%5Csqrt%7B%288%20-%20%28-8%29%29%5E%7B2%7D%2B%28-4%20-%20%28-7%29%29%5E%7B2%7D%7D%20)
![\sqrt{(8+8)^{2}+(-4+7)^{2}}](https://tex.z-dn.net/?f=%20%5Csqrt%7B%288%2B8%29%5E%7B2%7D%2B%28-4%2B7%29%5E%7B2%7D%7D%20)
