The answer is (x-42)×(x+42)
The jogger moves 5.4 mph / 60 = 0.09 miles per minute.
The 0.09 miles have to be divided by the length of one step.
Answer:
Step-by-step explanation:
<u>Given vertices WXYZ:</u>
- W(-4,5), X(2,4), Y(3, -4), Z(-1, -6)
Perimeter is the sum of the side length.
<u>Use distance formula to find each side:</u>
- WX =
≈ 6.08 - XY =
≈ 8.06 - YZ =
≈ 4.47 - WZ =
![\sqrt{(-1+4)^2+(-6-5)^2} =\sqrt{130}](https://tex.z-dn.net/?f=%5Csqrt%7B%28-1%2B4%29%5E2%2B%28-6-5%29%5E2%7D%20%3D%5Csqrt%7B130%7D)
≈ 11.40
<u>Find perimeter:</u>
- P = 6.08 + 8.06 + 4.47 + 11.40 = 30.01 units
