30 = 5(m) + 7(n)
5(a) + 30 = 7(a)
(a) is the number of visits!
15 = (a)
5(15) = 75 + 30 = 7(15) = $105

Answer:
1000 square feet.
Step-by-step explanation:
to find the area, you multiply the length by the width
40*25=1000
Answer:
length = 8
width = 4
Step-by-step explanation:
Area = length x breadth
Let x represent the width
length = x + 4
32 = x × (x + 4)
32 = x² + 4x
x² + 4x - 32 = 0
solving using quadratic equation =
(x² - 4x) -32 + 8x
x = 4 or -8
since width cannot be a negative number, we would use 4
