2(5x+7)+8x-7=27

We move all terms to the left:

2(5x+7)+8x-7-(27)=0

We add all the numbers together, and all the variables

8x+2(5x+7)-34=0

We multiply parentheses

8x+10x+14-34=0

We add all the numbers together, and all the variables

18x-20=0

We move all terms containing x to the left, all other terms to the right

18x=20

x=20/18

x=1+1/9

Y_Kistochka [10]

Answer:

12;16

Step-by-step explanation:

The Pythagorean theorem states that

a^2+b^2=c^2 where a and b are legs of a triangle, and c is the hypotenuse.

This means that we have to find 2 values that once squared, add up to 400. (20^2)

Based on this, we can use the values of 12 and 16 to satisfy this.

12^2+16^2=144*256=400

Therefore, the legs of the triangle are 12 and 16.
