Answer:32
Step-by-step explanation: -8*-4=32
1) perimeter = 36 ft
explanation:
p=2l+2w
p=2(8)+2(10)
p=16+20
p=36
area = 80 ft^2
explanation
a=l*w
a=8 ft* 10 ft
a=80 ft^2
2) perimeter = 28
explanation:
p=2l+2w
p=2(7)+2(7)
p=14+14
p=28
area = 49 in^2
explanation:
a=l*w
a=7in*7in
a=49 in^2
Answer:
INCORRECT
Step-by-step explanation:
Given a rectangular prism,
Total Surface Area = 2(LW+LH+WH)
If Length = 12, Width =20, and; Height = 16.
Total Surface Area = 2(12*20+12*16+20*16)
=2(240+192+320)
=2(752)
=1504
The Surface Area is 1504 Square Units, therefore if someone says the surface Area is 3,840, they are incorrect!
First subtract the constant to the other side to simplify it for now
y-5=-x^2+6x
Then pull out a common factor so the coefficient is x^2
y-5=-1(x^2-6x)
Next you take 1/2 of the b value (-6) and square it to find your c value
[1/2(-6)]^2=9
After that plug 9 into your equation as your c value
y-5=-1(x^2-6x+9)
Adding the C-value (9) causes the equations to become unbalanced so you need to balance them back out by minus 9 to the other side
y-14=-1(x^2-6x+9)
Now you want to simplify the equation on the right side.
y-14=-1(x-3)^2
Finally you want to add the constant back to the right side.
y=-1(x-3)^2+14 <——— vertex form
maximum=(3,14)
