Answer:
7^2 =49
Step-by-step explanation:
Exponents represent a number and how many times you multiply it by itself. So 5^2 is 5*5 or 4^3 is 4*4*4. So 7^2 is 7*7, which is 49!
4x +28 and 68 are vertical angles and are equal.
Set them to equal each other to solve for x:
4x +28 = 68
Subtract 28 from each side:
4x = 40
Divide both sides by 4:
x = 40/4
x = 10
