L=1.5w. And the perimeter of a rectangle is 2w+2l=25 substitute the 1st equation into the second.2w+2(1.5w)=252w+3w=255w=25W=5
The new equation is 
Explanation:
The equation is 
We need to determine the new equation by adding 16 to both sides of the equation.
Hence, we shall increase both sides of the equation by 16, we get,
Adding, we get,
Hence, the new equation is
Answer:
6 ± i and 6 ± i
Step-by-step explanation:
Let x be the first number.
Let y be the second number.
x + y = 12
x × y = 37
Solve for x in the first equation.
x = 12 - y
Put x as 12-y in the second equation and solve for y.
(12- y)y = 37
12y - y² = 37
- y² + 12y - 37 = 0
y = 6 ± i
Put y as 6 ± i in the first equation and solve for x.
x + 6 ± i = 12
x = 12 - 6 ± i
x = 6 ± i
The given point C is the Center
