46: 24a+40
First we are going to take a look at a) 8(3a+5)
a) We then simplify it by multiplying the numbers inside the parenthesis by 8.
a) 24a+40
Now we ask ourselves, is this equivalent to 24a+40? YES!
So your answer for #46 is a) 8(3a+5)
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:
y = 1/2
Step-by-step explanation:
<u>Step 1: Solve for y</u>
2y + 3 = 4y + 2
2y + 3 - 2 - 2y = 4y + 2 - 2 - 2y
1 / 2 = 2y / 2
1/2 = y
Answer: y = 1/2
-4x is the coefficient, 7 is the constant and x is the variable
