a rectangle with length and width equal is a square.
32/4 sides
equals 8 for each side.
l x w = A
8 x 8 = 64
56+9-3*2
56+9-6
59
.........
Set height to x, then length of base is x+3, Area formula says that
0.5*x*(x+3)=44, x(x+3)=88, x=8, x+3=11, which is the length you are looking for (11cm)
A landscape service charges
customers a one time fee and an hourly rate of $15. For 3 hours of work, it
charges $75. Using the given data the one time fee can be solve:
75 = 3(15) + b
b = 30
<span> so the equation of the line </span>
y = 15 x + 30
<span>so the charge for 10 hrs is
equal to $180</span>
