Answer:
see below
Step-by-step explanation:
the point-slope equation is
y-1 = 3/2 (x+4)
The answer is x = 9
My first step in solving this is dividing 15 by 5.<span />
18,000. When the place before the number you are trying to round to is less that 5, that round down. If its is 5 or more, then round up.
Split it up into 3 separate shapes.
Rectangle 1 = 15 x 3 = 45
Rectangle 2 = 3 x 5 = 15
Triangle = 1/2 x 5 x 3 = 7.5
Total area = 45 + 15 + 7.5 = 67.5 cm²
