Answer:
-2x² + 4x + 2
Step-by-step explanation:
(1-8x²+3x)+(1+6x²+x)
= 1 - 8x² + 3x + 1 + 6x² + x
= -2x² + 4x + 2 [-2(x² - 2 - 1)]
Answer:
11 + x = 28
Step-by-step explanation:
The number of books they bought must add to 28.
Answer:
X=42
Step-by-step explanation:
AB and BC make a right angle
So, 24°+x+24° =90°
48°+x=90°
X=90°-48°
X=42
To solve for s all you have to do is factor the 7 and simplify the rest.
7s-21=21
7s=42
s=6
