The area of a rectangular wall of a barn is 75 75 square feet. its length is 10 10 feet longer than the width. find the length a
nd width of the wall of the barn.
1 answer:
A = L * W
A = 75
L = W + 10
75 = W(W + 10)
75 = W^2 + 10W
W^2 + 10W - 75 = 0
(W + 15)(W - 5) = 0
W + 15 = 0
W = -15...not this one because it is negative
W - 5 = 0
W = 5 <=== width is 5 ft
L = W + 10
L = 5 + 10
L = 15 <=== length is 15 ft

Answer:
point = (-3, 5)
slope = 3/4
Step-by-step explanation:
The formula for point slope is:
y - y1 = m (x - x1)
point (x1, y1)
slope m
So with your equation:
y - 5 = 3/4 (x+ 3)
point = (-3, 5)
slope = 3/4
