Let l be the length of the parcel of land. Recall that the area of a rectangle is the product of its length and width:
Substitute A=1125 square feet and w=25 feet:
So, the length of the parcel of land is 45 feet.
To find the lowest original score that will result in an A if the professor uses
\((i)(f \times g)(x)\ and\ (ii)(g \times f)(x)\).
Professor Harsh gave a test to his college algebra class and nobody got more than 80 points (out of 100) on the test.
One problem worth 8 points had insufficient data, so nobody could solve that problem.
The professor adjusted the grades for the class by
a. Increasing everyone's score by 10% and
b. Giving everyone 8 bonus points
c. x represents the original score of a student
