Answer:
First add all the equations like (11y-32)+(3x-16)+(6x+7)=180
Step-by-step explanation:
You would first combine all the like terms so put all the variables on one side and the numbers on the other. After you have done that, you would just solve.

Answer: Choice A</h3>
The area of square T is equal to the sum of the areas of square R and square S.
=======================================================
Explanation:
Recall that the pythagorean theorem says
a^2+b^2 = c^2
Visually this means if we had a square with side length 'a', then its area is a^2. The same goes for a square with side length b. Its area is b^2
So a^2+b^2 is the sum of those square areas. It being equal to c^2 tells us that adding the smaller square areas lead to the largest square area.
So that's why the areas of squares R and S add up to the area of square T.

An example:
Let's say...
- square R has side length 3
- square S has side length 4
- square T has side length 5
note how 3^2+4^2 = 9+16 = 25 and how 5^2 = 25. This shows 3^2+4^2 = 5^2
Answer:
x = 138
Step-by-step explanation:
The 2 arcs above the diameter form a semicircle = 180°
x + 42 = 180 ( subtract 42 from both sides )
x = 138
