In order to simplify a fraction, we have to find a common factor in both numerator and denominator. So, let's start by factor the expressions completely: at the numerator we have
At the denominator we have
So, the fraction can be written as
You can see that there is a factor in common, that can be simplified:
Answer: cant see it
Step-by-step explanation:
Lets find the missing sides first
big triangle, we apply the Pythagorean theorem a^2+b^2=c^2
a^=13^2-5^=169-25=144, Square root of a=square root of 144=12
a=12
smaller triangle
5^2-3^2=b^2
25-16=9
b=4

Answer:
The brown paper weighs 80 ounces.
Step-by-step explanation:
Since the brown paper takes up 1/4 of the 20 pounds of paper in the box, there are pounds of brown paper.
We know that 1 pound = 16 ounces, so 5 pounds of brown paper weighs 5 * 16 = 80 ounces.
The brown paper weighs 80 ounces.
