Answer:
Step-by-step explanation:
Given the total cost of the building expressed as;
C = 4550F + 37.5
C is the total cost
F is the length of the fence
Given
C = $352.50
Required
The length of the fence F
Substitute into the formula;
C = 4550F + 37.5
$352.50 = 4550F + 37.5
4550F = 352.50 - 36.5
4550F = 316
F = 316/4550
F = 0.0695 feet
hence 0.0695 feet of fence will cost $352.50
Answer:
390 ft²
Step-by-step explanation:
25x10= 250
20x7= 140
250+140= 390
Answer:
they are equal because while solving 2b+5+1b it will come 3b+5 so they are equal
Answer:a2+b2=c2
32+42=52
9+16=25
25=25
Step-by-step explanation:
Answer: 4 x (12 - 8)
Step-by-step explanation:
the word difference really means exactly what it is saying. it is the quantity difference between two numbers. like, if someone would say, "what's the difference between 4 and 2?' then you would just subtract 2 from 4 to find the difference between the two numbers.
so, we now know that we are going to be subtracting 8 from 12.
plus, it tells us to show 4 times 12 - 8. that means that we will be multiplying (12 - 8) by 4.
so, our only viable option is 4 x (12 - 8).
