Answer:
8
Step-by-step explanation:
-4x+8+2x
2x+8
compare both sides
2x+__= 2x+8
it is 8
Answer:
-108
Step-by-step explanation:
-8 - ( -10 )²
= -8 - 100
= -108
To find the length of the side of a square when the area is known, find the square root of the area:
Side length = √729
Side Length = 27 feet.
X^2-11x+28=0
(x-7)(x-4)=0
x-7=0
x=7
x-4=0
x=4
It is understood without being written that the slope of this line is 1. If we rewrite the point-slope form of the line it would be y-8=1(x-4) where 1 is the slope. We move the -8 over by addition to get y = 1x-4+8, or, simplified, y=x+4, the first choice in your answers.
