Answer:
A. -16x²+64x+8
B. 72 ft.
Step-by-step explanation: A. Expand the perfect square binomial -16(x²-4x+4)+72, dist. -16 (-16x²+64x-64+72), then combine like terms (-16x²+64x+8)
B. Find the abs. max. by looking back at the vertex form. The max is (2,72). Use the y-value for the height.
18 ? am not really sure tho its kinda difficult lol
The answer is -25
All you have to do is add -6-9 which equals -25 because “same signs add(+) and keep” “different signs subtract(-)” but “add” means positive number and “subtract” means negative number. Since they are different signs a (+) and a (-) you subtract it.
Hope this helps!
Answer:
m < −4/3
Step-by-step explanation:
−5(3m−2)>30
Simplify both sides of the inequality.
−15m+10>30
Subtract 10 from both sides.
−15m+10−10>30−10
−15m>20
Divide both sides by -15.
−15m/−15 > 20/−15
m<−4/3
