Answer:
![4\left(2x+7\right)-3\left(x+5\right)=5x+13](https://tex.z-dn.net/?f=4%5Cleft%282x%2B7%5Cright%29-3%5Cleft%28x%2B5%5Cright%29%3D5x%2B13)
Step-by-step explanation:
Given the expression
![4\left(2x+7\right)-3\left(x+5\right)](https://tex.z-dn.net/?f=4%5Cleft%282x%2B7%5Cright%29-3%5Cleft%28x%2B5%5Cright%29)
<u>Expand and simplify the expression</u>
![4\left(2x+7\right)-3\left(x+5\right)](https://tex.z-dn.net/?f=4%5Cleft%282x%2B7%5Cright%29-3%5Cleft%28x%2B5%5Cright%29)
Expand 4(2x + 7) = 8x + 28
![4\left(2x+7\right)-3\left(x+5\right)=8x+28-3\left(x+5\right)](https://tex.z-dn.net/?f=4%5Cleft%282x%2B7%5Cright%29-3%5Cleft%28x%2B5%5Cright%29%3D8x%2B28-3%5Cleft%28x%2B5%5Cright%29)
Expand -3(x + 5) = -3x - 15
![=8x+28-3x-15](https://tex.z-dn.net/?f=%3D8x%2B28-3x-15)
Group like terms
![=8x-3x+28-15](https://tex.z-dn.net/?f=%3D8x-3x%2B28-15)
Add similar elements: 8x - 3x = 5x
![=5x+28-15](https://tex.z-dn.net/?f=%3D5x%2B28-15)
Simplify
![=5x+13](https://tex.z-dn.net/?f=%3D5x%2B13)
Therefore, we conclude that:
![4\left(2x+7\right)-3\left(x+5\right)=5x+13](https://tex.z-dn.net/?f=4%5Cleft%282x%2B7%5Cright%29-3%5Cleft%28x%2B5%5Cright%29%3D5x%2B13)
9. You shouldn't agree, because they are equal to one another.
10. 84 cents plus 61 should be $1.45 because 84 + 61 is 145 and 100 cents equals 1 dollar, and then you have 45 left over.
100 - .63 is .37 because the whole painting is equal to 1, or .1, or in this case I used it as 100. The drawing is up to you, but you can just draw a canvas and shade in a little bit more than half but not the full canvas. .37 of the canvas is left.
AB = sqrt(10^2 - 4^2) = sqrt(100 - 16) = sqrt(84) = sqrt(4 x 21) = 2sqrt(21) = 2 radical 21.
