Answer:
7x + 34 = 90
-34 -34
7x = 56
Divide by 7 on both sides:
X = 8 degrees
A right angle equals 90 degrees so that must mean angle 7x + 34 must equal to 90 so we solve for x.
A triangle equals = 180 degrees
A quadrilateral equals = 360 degrees
A right angle equals = 90 degrees
A straight line equals = 180 degrees
Answer:
7d - 28
Step-by-step explanation:
Answer:
4=0
Step-by-step explanation:
Simplifying
(-9p + 7) + -1(-9p + 3) = 0
Reorder the terms:
(7 + -9p) + -1(-9p + 3) = 0
Remove parenthesis around (7 + -9p)
7 + -9p + -1(-9p + 3) = 0
Reorder the terms:
7 + -9p + -1(3 + -9p) = 0
7 + -9p + (3 * -1 + -9p * -1) = 0
7 + -9p + (-3 + 9p) = 0
Reorder the terms:
7 + -3 + -9p + 9p = 0
Combine like terms: 7 + -3 = 4
4 + -9p + 9p = 0
Combine like terms: -9p + 9p = 0
4 + 0 = 0
4 = 0
Solving
4 = 0
If you're simplifying, it would be 16z+10 squared.
