Answer
Find out the original side length of the square .
To prove
Let us assume that the original length of the square be x.
Formula

As given
The dimensions of a square are altered so that 8 inches is added to one side while 3 inches is subtracted from the other.
Length becomes = x + 8
Breadth becomes = x -3
The area of the resulting rectangle is 126 in²
Put in the formula
(x + 8) × (x - 3) = 126
x² -3x + 8x -24 = 126
x ²+ 5x = 126 +24
x² + 5x - 150 = 0
x² + 15x - 10x - 150 = 0
x (x + 15) -10 (x +15) =0
(x + 15)(x -10) =0
Thus
x = -15 , 10
As x = -15 (Neglected this value because the side of the square cannot be negative.)
Therefore x = 10 inches be the original side of the square.
Answer:
it 8
Step-by-step explanation:
4^3 is 64
2^3 is 8
64/8 is 8
Sllope intercept form is y=mx+b
m is the slope , b is the y itnercept
so early pay
cost=70 flat rate
x=infinity
the equation would be y=70
deposit pluss
you have to pay an initial one time payment of 15 so
y=mx+15
then 4 dollars per day
4 times number of days
y=4x+15
daily pay is 6 dollars per day so 6 times number of days
y=6x
1.
a. y=70
b. y=4x+15
c. y=4x
