Answer:
Step-by-step explanation:
new length=15+x
width=19+x
then area=(15+x)×(19+x)=285+15x+19x+x²=x²+34x+285 ft²
original area=15×19=285 ft²
then 285+98=x²+34x+285
or
x²+34x-98=0
x²+34x+17²=98+17²
(x+17)²=98+289=387
x+17=√387=3√43
x=3√43-17 ft
60-3d + 20-6 =4d
74-3d =4d
-3d =4d -74
-7d = -74
D=74/7
Answer:
The value of x in terms of b is: 
The value of x when b is 3 is: x = -1
Step-by-step explanation:
We are given the function: 
First we need to find
The value of x in terms of b
We need to find value of x

Multiply -2 with terms inside the bracket

Subtract 10 from both sides

Divide both sides by -2b

So, The value of x in terms of b is: 
The value of x when b is 3
We have the equation for the value of x in terms of b:

Put b = 3

So, The value of x when b is 3 is: x = -1
So to solve for y, subtract 108 from each side.
The equation becomes -y=126
Since you don't want y to be negative then divide each side by -1 this will flip all of the signs (positives become negative and vice versa) without changing the number.
So the equation is now y= -126
