If 34% of a book is 85 pages the entire book is 250 pages. This means that if she read 85 pages she has 165 pages left to read.
We can use the Pythagorean Theorem to solve this:
a^2 + b^2 = c^2 ( a and b are the sides and c is the hypotenuse)
We can fill in what we know and solve:
36^2 + b^2 = 85^2
1296 + b^2 = 7225
b^2 = 7225 - 1296
b^2 = 5929
b = SQRT(5929)
b = 77
The other leg is 77 meters long
The CORRECT answer is::
x = -3 and x = -7
WORK::
Move ALL terms to the left side and set equal to zero. Then set each factor equal to zero.
