Width= w
lenght = 6 width = 6w
area= 284 yd²
= (width)(length)
= (w)(6w)
= 6w²
6w²= 284
w²= 284/6
= 47.333333....
w=√47.2
= 6.88 inches
perimenter = 2width+ 2 lenght
= 2(w) + 2(6w)
= 2w+12w
= 14w
= 14(6.88)
= 96.28 inches
618,792 could have been the exact population.
since you are rounding to the nearest ten thousand, you would round my number up.
Remember to make the polynomials to equal zero, one or the other polynomial must equal zero. So...
2x-3 = 0
2x= 3
x=3/2
and
4x+5 = 0
4x = -5
x = -5/4
So the answers are x=3/2 and x = -5/4
Hope this helps!
