Step-by-step explanation:
First, transform 8 feet and 10 feet into inches so we can work with the same measurements
8 * 12 = 96 in
10 * 12 = 120 in
Next find the patio rectangle area.
96 * 120 = 11520 in^2
Now find the paving block area
4 * 8 = 32 in^2
Now, find out how many paving blocks will go into the patio rectangle area.
11520 / 32 = 360
The minimum number is 360 paving blocks
Answer: (r + 4)(r + 8)Alright, I would first rearrange the equation by bringing all your terms to one side by adding 12r and 32 to both sides. This will result in the rearranged equation:

You can then factor the equation into the two binomials:
(r + 4)(r + 8).
4 + 8 equals the b term, 12, and 4 x 8 equals the c term, 32.
Answer:

Step-by-step explanation:
Answer:
Step-by-step explanation:
1) y = 50x + 2500
2) y = 200x + 1000
if we build a system with the two equations, we have:
50x+2500 = 200x + 1000
150x = 1500
x = 10
y = 2000 + 1000 = 3000
3) 10
4) $3000
