7 ft 6 in = 90 in
10t ft = 120 in
A = 90 x 120 = 10800 in^2
10800 in^2 = 75 ft^2
answer
C. 75 ft^2
5(1.60+0.80)
(8+4)
12
Therefore Michelle spends 12 dollars in 5 days
if you're solving for x,
start by isolating x squared to get
x^2 = 16 (we added 8 to both sides)
then square root each side:
sqrt of x^2 = x; sqrt of 16 = 4.
we end up with x = 4 (positive and neg)
if you're factoring
minus 8 from both sides to get
x^2 - 16
from there we can factor to get
(x + 4)(x - 4)

Complete question :
Imagine you are starting an office supply business. Your overall costs for supplies are $100. You plan on selling binders for $4 each and pencils for $2 each. Let x represent the number of binders sold and y represent the number of pencils sold. Give an expression for the profit made.
Answer:
(2y + 4x) - $100
Step-by-step explanation:
Given that:
Cost of supply = $100
Supplies :
binders, sales price = $4
Pencils, sales price = $2
Number of binders sold = x
Number of pencils sold = y
The revenue from sale :
(Cost of pencils * number of pencils) + (cost of binders * number of binders)
Revenue = 2y + 4x
Profit, p = Revenue - Cost of supply
p = (2y + 4x) - $100
