Answer:
1075 sq ft
Step-by-step explanation:
There are a few ways to do this but I am only going to show one.
35 x (25 + 8) - (5 x 8 + 8 x 5) = 1155 - 80 = 1075
Answer:
(3x-2)(4x-1)
Step-by-step explanation:
1. take the a and the c value and multiply them together to isolate x^2. it should be x^2 -11 +24.
2. find what multiplies to 24 and adds up to -11. its -8 and -3.
3. factor like normal and get (x-8) (x-3)
4. divide the -8 and -3 in the factors by 12 (the original a value)
-8/12 = -2/3 and -3/12 = -1/4.
5. the denominator gets moved to the x value to get (3x-2)(4x-1)
An easier way to think of this problem is just keep adding for each additional hour:
0.5 hours --> $2
1.5 hrs --> $3.75
2.5 hrs --> $5.50
3.5 hrs --> $7.25
and since you can only spend $7, the maximum time is 2.5 hours
