Answer:
4 miles
Step-by-step explanation:
In 7 minutes he runs 1 mile
So in 28 minutes he runs 4 miles
<u>How did I get this answer?</u>
7×4=28
So 1×4=4
In ratios, when you times anything by something, you must do the same to the other part of the ratio.
Here is your answer:
4x² + 28x + 49
4x² + 14x + 14x + 49
2x(2x) + 2x(7) + 7(2x) + 7(7)
2x(2x + 7) + 7(2x + 7)
(2x + 7)(2x + 7)
(2x + 7)²
= 28
Hope this helps!
