Answer:
Surface area of the refrigerator is 864 in².
Step-by-step explanation:
Formula to calculate the surface area of a cube is,
Surface area = 6s²
Here, s = length of a side of the cube
If side length 's' = 12 inches
By substituting this value in the formula,
Surface area = 6(12)²
= 6 × 144
= 864 inch²
Therefore, surface area of the refrigerator is 864 in².

64,120,136
I think
Step-by-step explanation:
An easy way to do this is by using the simplest equations you can:
x + y and x - y
(3, 5) is (x, y). all you have to do is plug those into your equations and get a result, so:
x + y = 8
(because 3 + 5 = 8)
x - y = -2
(because 3 - 5 = -2)
and those can serve as your system of equations.
you can check it by solving by substitution:
x - y = -2
x + y = 8
solve one of the equations for a single variable:
x = y - 2
plug it into the second equation:
(y - 2) + y = 8
y - 2 + y = 8
2y - 2 = 8
2y = 10
y = 5
then plug that result back into the equation:
x + y = 8
x + 5 = 8
x = 3
Answer:
The price of fertilizer is $27.5 and potting soil is $5
Step-by-step explanation:
I think that you are asking for the price of each bag of fertilizer and potting soil. And here is my answer:
Given the system of linear:
3s + 4f = 125 <=> f = 31.25 -3/4s (1)
4s + 2f = 75 <=> f = 37.5 -2s (2)
Take (1) -(2) we have:
f -f = 31.25 -3/4s - (37.5 -2s)
<=> 0 = -6.25 + 1.25s
<=> 1.25s = 6.25
<=> s = 5
=> f = 37.5 -2(5) = 27.5
So the price of fertilizer is $27.5 and potting soil is $5
