7x-7-2x-2+3x-12=8x-21
I think
The answer to your math problem is C. The reason being is 2x times x is 2x^2 and 2x times 11 is 22x. So you first part of the problem looks like 2x^2+22. Then -6 times x is -6x and -6 times 11 is -66. So now the problem is 2x^2+22x-6x-66. So your answer after solving it is 2x^2+16x-66.
It either B or D. zoz dnd keep
Answer:
m=7
m−2
5
=
m−4
3
(m−2)*(3)=(m−4)*(5)
3m−6=5m−20
Step 2: Subtract 5m from both sides.
3m−6−5m=5m−20−5m
−2m−6=−20
Step 3: Add 6 to both sides.
−2m−6+6=−20+6
−2m=−14
Step 4: Divide both sides by -2.
−2m
−2
=
−14
−2
m=7

Answer:
Step-by-step explanation:
<u>Volume formula will be:</u>
where V - volume, k - coefficient of proportion, r² - squared radius, h - height
<u>Substitute the known values to find the unknown:</u>
- 62.8 = k*4*5
- 62.8 = 20k
- k = 62.8/20
- k = 3.14
<u>Now find the volume of the taller can:</u>
- V = kr²h
- V = 3.14*4*9 = 113.04 ≈ 113 in³
Correct option is A
