Answer:
The answer of the question is 5
<span>L = 2W + 5
A = LW = 63
L = 63/W
W=63/L
L = 2W + 5
63/W = 2W + 5
63 = 2WW + 5W
2WW + 5W - 63 = 0
2WW + 5W - 63 = 0
is already in quadratic equation form: ax^2 + bx + c = 0
use the quadratic formula to solve for two solutions:
x = ( -b +- sqrt( bb - 4ac ) ) / 2a
the two solutions are:
x = 9/2
x = -7
you cant have a negative solution for length so use the positive one
solve for length:
L=5+2(9/2)
L=5+18/2
L=5+9
L=14
W = 9/2
L = 14</span>
Answer:
81
Step-by-step explanation:
So first find the are of the rectangle: 9 * 15 = 135
Next find the area of the trapezoid.
135 - 54 = 81
Huh? What are you saying?
Graph a.
3x+2y=12
-3x -3x
2y=-3x+12
2/2y=(3x+12)/2
y=-1.5x+6
graph b.
4x-y=5
+y +y
4x=y+5
-5 -5
4x-5=y
c) 11 units is the difference between y-coordinates of graph a and y-coordinates of graph b.
e) at (6,-3) x=6 cuts into graph a
