Answer:
x=4
Step-by-step explanation:
f(x) = x^2 - 8x+16
Set equal to zero
0 = x^2 -8x +16
Factor
what 2 numbers multiply to 16 and add to -8
-4*-4 = 16
-4+-4 = -8
0= (x-4)(x-4)
Using the zero product property
x-4 = 0 x-4 =0
x=4 x=4
We know that the formula for the volume of a box is:

Where:
l = length
w = width
h = height
The formula of the surface area of a box is:

Based on the given we know the following:

and

If we factor out the given volume, you can come up with 3 numbers that will satisfy the surface area formula:

Let:
l = 6cm
w = 7cm
h = 13cm
Now let's try this on the surface area formula:





The answer is then:
l = 6cmw = 7cmh = 13cmAny order would be fine.
Answer:
1st, 2nd, and last.
Step-by-step explanation:
For the first two common rules can be applied such as
=
and that
and for the last one this is just simplifying the radical and if you factor it you realize that,
meaning that you can take the radical off of 5/8 and end up with that final answer
The correct answer is 42x^4-24x^3+12x^2
