Answer:
X- int (11/2,0) Y-int (0,-11)
X-int (5/2,0) Y-int (0, -5)
6(13m+3-5/6m=-15)
78m+18-5m=-90
73m+18=-90
73m= -108
m = -108/73
Answer: 4x2 + 32x − 80 = 0
Step-by-step explanation:
Area of a rectangle is given by
A = l*w
The length is (2x+10) and the width is (2x+6)
A = (2x+10)(2x+6)
FOIL
first 2x*2x = 4x^2
outer 2x*6 =12x
inner 2x*10 =20x
last 10*6=60
Add this together
4x^2 +12x+20x +60 = 4x^2 +32x+60
This must equal 140 inches
4x^2 +32x+60 = 140
Subtract 140 from each side
4x^2 +32x+60-140 = 140-140
4x^2 +32x -80=0
Here, 4x + 6 = 38
4x = 38 - 6
x = 32 / 4
x = 8
In short, Your Answer would be Option B
Hope this helps!
There are two answers for this question:
(-6,10)
(-6,-10)
because it doesn't say which direction the units go, it could be either of them, therefore type both answers in the box.
