Answer:
2x² +2x - 12
Step-by-step explanation:
area of rectangle = length X width
length = x+3
width = 2x - 4
Area = (x+3)(2x-4)
= x(2x-4) +3(2x-4)
= 2x² - 4x + 6x - 12
= 2x² +2x - 12
Answer:
Y intercept is x=0 so y=Mx+b your b is the y intercept
Step-by-step explanation:
I think 71 is B
and 72 is D.
Answer:
Step-by-step explanation:
x + (x + 3) +
= 75
so you will add up all of the x 's but NOT the x^2
2x + 3 +
= 75
Rearrange to put the x^2 in front of 2x
+ 2x + 3 = 75
subtract the 75 from both sides
+ 2x - 72 = 0
