Answer:
This is true when the shape is a cube because all the faces are equivalent. This isn't true when it is a rectangular prism because some faces have areas larger than other faces.
Step-by-step explanation:
<span>x = –4c
</span>if c = -2 then x = -4(-2) = 8
I believed you had a typo, function should be f(x) = -3x^2 - 4x
so
<span>f(x) = -3x^2 - 4x
</span>f(x) = -3(8^2) - 4(8)
f(x) = -3(64) - 32
f(x) = -192 - 32
f(x) = -224
answer
<span>C.
–224</span>
Answer:
100 percent
Step-by-step explanation:
The value 40 increases to 80 meaning it doubles its value by one hundred percent.
Answer:
1.30
Step-by-step explanation:
3+5x=7
Subtract 3 on both sides, 3 will cancel out on the left side and will subtract by 7 making it 4
5x=4
Then divide by 5 on both sides to isolate the x.
5/4=1.25
1.25 rounds to 1.3

Answer:
w=16, L=20
Step-by-step explanation:Length(L)=w+4
P=72
P=2L+2w
P=2(w+4)+ 2w
P=2w+8+2w
72=4w+8
4w=72-8
4w=64(/4)
w=16
L=16+4=20
Verification: 16+16+20+20=72
32+40=72
72=72 (T)
