Question 200373
Area of a painting. A rectangular painting with a width of
x centimeters has an area of x^2 +50x square centimeters.
Find a binomial that represents the length. See the accompanying
figure.
.
Since,
length*width = area
.
Given:
width = x
area = x^2 + 50x
.
Plug in what was given:
length(x) = x^2 + 50x
dividing both sides by x:
length = x + 50  (this is what they're looking for)
