Answer:

Step-by-step explanation:
* Look to the attached file
Area of triangle=1/2(base×height)
360=1/2((4x-2)(7x+5))
720=(4x-2)(7x+5)
FOIL the binomial
720=28x^2+6x-10
Bring 720 to the other side
28x^2+6x-10-720=0
28x^2+6x-730=0
Factor 2 out
2(14x^2+3x-365)=0
Factor 2(14x+73)(x-5)=0
x-5=0
x=5
It can't be 14x-73=0 because the length can't be negative.
You're welcome.
First,
149,500 * .10 = 14,950
149,500 - 14,950 = 134,550
then,
134,550 * .05 = 6727.50
134,550 - 6727 = 127,822.55
127,822.50 * .04 = 5112.90
trade discount = 14950 + 6727.50 + 5112.90
26790.40
hope this help
