Answer:
x = 3 or x = 1
Step-by-step explanation:
Solve for x over the real numbers:
x^2 - 4 x + 3 = 0
Subtract 3 from both sides:
x^2 - 4 x = -3
Add 4 to both sides:
x^2 - 4 x + 4 = 1
Write the left hand side as a square:
(x - 2)^2 = 1
Take the square root of both sides:
x - 2 = 1 or x - 2 = -1
Add 2 to both sides:
x = 3 or x - 2 = -1
Add 2 to both sides:
Answer: x = 3 or x = 1
First term is 2 and the common difference is the value by which it increases which is 2.

Answer:
8x+16 ft^2
Step-by-step explanation:
First we find the total area of the large rectangle
A = l*w
A = (x+3) * (x+5)
FOIL
A = x^2 +5x+3x+15
A = x^2 +8x+15
Now we find the area of the inner rectangle
A = lw
A = (x+1) (x-1)
FOIL
A = x^2 -x+x -1
A = x^2 -1
To find the shaded area, take the large rectangle and subtract the small rectangle
x^2 +8x+15 - (x^2 -1)
Distribute the minus sign
x^2 +8x+15 - x^2 +1
Combine like terms
8x+16
