Area of rectangle =wxl
A=(3x+5)(x-3)
A=3x^2+5x-15-9x
A=3x^2-4x-15
Multiply first equation with 2. Then add first and second, we get -x=6. X=-6 and y=-29
Sold 2/5 in the morning.....leaving 3/5
he sold 3/4 of 3/5 in the afternoon......3/4 * 3/5 = 9/20
2/5 = 8/20
9/20 - 8/20 = 1/20...so he sold 1/20 more in the afternoon.
so if 1/20 = 24, then 20/20 = 24*20 = 480
so he started with 480 cartons
Step-by-step explanation:
first inequality :
x + 2y ≥ 10
second inequality :
x - y ≤ -2
