Hey there!
It is said we need to find the unit rate.
What we can do is apply Unitary Method.
3 minutes = 42 push ups
1 minute = 
<u>So, 12 push ups per minute is the unit rate.</u>
In 5 minutes, he will do 12×5 = <u>60 push ups!</u>
Hope it helps :)
In a rational function, holes are located where f(x) is undefined(the denominator is 0), but the undefined points can be factored out. In f(x), when x is 4 or -3, f(x) is undefined. But, x+3 can be factored out, so it is a hole. The hole is located at (-3,-1/7)
The answer to this question is d because 7 is in the ten-thousand's place and another 7 is in the thousand's place.
Answer: 
Step-by-step explanation:
1. The formula for calculate th area of a square is shown below:

Where s is the side of the square.
2. Therefore, if the square tabletop has side lengths of (4x-8) units you have:

3. By definition, the square of a binomial is always a trinomial:

4. Then, you obtain:

Yes. When simplifying 15:60 by dividing each side by 3, you get 5:20, which is the same as 5:20.
