Answer:
To get to -3 you can do 1+-4
A(area) = b(base) * h(height)
A = 56 * 157
A = 8,792 mi^2
X= 2/3
6x/x-6 - 4/x - 24 / x^2 - 6x = 0
6x^2 -4 (x-6)-24 / x(x-6) = 0
6x^2 -4x+ 24 -24/x(x-6) = 0
X(6x-4) / x(x-6)
6x-4/x-5 = 0
6x-4= 0
6x = 4 divide both sides by 6
X= 2/3
9.75 * 1.2 = 11.7
24.5 * .8 = 19.6
11.7+19.6= 31.3 minutes
hope this helped :)
