5-2(y+1)=21
Distribute
5-2y-2= 21
Combine like terms
3-2y=21
Subtract 3 from both sides
-2y= 18
Divide both sides by -2
y= -9
Final answer: y=-9
So if im correct you would times
5.5*^4
Answer:
9x² + 28x - 32
Step-by-step explanation:
Given
(9x - 8)(x + 4)
Each term in the second factor is multiplied by each term in the first factor, that is
9x(x + 4) - 8(x + 4) ← distribute both parenthesis
= 9x² + 36x - 8x - 32 ← collect like terms
= 9x² + 28x - 32
The actual answer is 1280.5 but it says estimate. I would put something like 1281 or 1279 as your final answer because your just estimating. I hope this helped.
Answer: 1281
