Answer:
70+30x-140
Step-by-step explanation:
(7x+3) (10x-14)
70-98+30x-42
70+30x-42-98
x = 9
These are vertical angles, and thus the angles are equal.
7x + 3 = 10x - 24
Combining like terms, we get
27 = 3x, so that x must be 9.
P = 2x + 7
5 squares the times it by pi (pi equals 3.14 btw)
5 squared is 25
y=x^2+8
