The answer is 8 m by 16 m. I just answered this on my quiz.
Hello,
With
y=x²-4x-21
y=-5x-22
==>x²-4x-21=-5x-22
==>x²+x+1=0
In R, no solution for Δ=1-4=-3<0
The y-intercept is (0, 7) the x-intercept is (-3, 0)
Your answer is B
I would say the second step would be maybe to start the physical activity,or to write down which days you're going to do them.
