Answer:
16y - 4
Step-by-step explanation:
4y(4y - 4) - 4(- 4 + 5 + 4y^2)
16y - 16y - 4(1 + 4y^2)
16y - 16y - 4(4y^2 + 1)
16y^2 - 16y^2 + 4
16y - 4

Answer:
Idk I need the answer too
Step-by-step explanation:
The numbers are: 2n and (2n+2)
we can suggest this equation:
4(2n)=2(2n+2)-12
We compute this equation:
8n=4n+4-12
8n-4n=-8
4n=-8
n=-8/4
n=-2
we compute the numbers:
2n=2(-2)=-4
2n+2=-4+2=-2
answer: the numbers are -4 and -2.
Answer:
<h2>1. V = 100 in³</h2><h2>2. h = 10 in</h2>
Step-by-step explanation:
The formula of a volume of a cylinder:

<em>B</em><em> - base area</em>
<em>h</em><em> - height</em>
<em />
1. We have
<em>h = 5in, B = 20 in²</em>.
Substitute:

2. We have
<em>B = 20.7 in², V = 207 in³</em>.
Substitute:
<em>divide both sides by 20.7</em>
