Answer:
L = 16 W=3
Step-by-step explanation:
Let width = x
Length = 4x +4
Area = 48
Area = L times w
48= (4x+4)(x)
48 = 4x^2 +4x
0 = 4x^2 +4x -48
0= 4(x^2 +x-12)
0 = (x+4)(x-3)
x = -4
x=3
Ignore the -4 because it's unrealistic to have negative length width or area
Hence, only solution is 3
Width = 3
Length = 4x + 4 = 4(3) + 4 = 12+4 = 16
Hope this helps!

(-9) - (-2) = -7
that should be the answer you subtract
I have checked this alot of times and I can never seen the pic....
Answer:
y = x + 15
Step-by-step explanation:
If two lines are perpendicular to each other, they have opposite slopes.
The first line is y = - x - 2. Its slope is -1. A line perpendicular to this will have a slope of 1.
Plug this value (1) into your standard point-slope equation of y = mx + b.
y = 1x + b or y = x + b
To find b, we want to plug in a value that we know is on this line: in this case, it is (-5, 10). Plug in the x and y values into the x and y of the standard equation.
10 = (-5) + b
Simplify.
10 = -5 + b
Now, add 5 to both sides to isolate b.
15 = b
Plug this into your standard equation.
y = x + 15
This equation is perpendicular to your given equation (y = -x - 2) and contains point (-5, 10)
Hope this helps!
Apples went up 0.75 a lb
p is the start price so new price is p + 0.75
we buy 3 lbs
3 ( p+ 0.75) = 5.88
now solve
3p + 2.25 = 5.88
-2.25 -2.25
3p = 3.63
/3 /3
p = 1.21 a lb
