Answer:
C = 24
Step-by-step explanation:
(x - 6)² - 12 = x² - 12x + c
(x - 6) (x - 6) -12 = x² - 12x + c
x(x - 6) - 6(x - 6) - 12 = x² - 12x + c
x² - 6x -6x + 36 - 12 = x² - 12x + c
x² - 12x +36 - 12 = x² - 12x + c
x² - 12x + 24 = x² - 12x + c
24 = c

Answer:
20 in²
Step-by-step explanation:
Assuming that the width of the sign is x, then from the question, we're told that the length is 5 times it's width, so
b = x inches
l = 5x inches
Again, we're told that the perimeter of the sign is 24 inches, and we know already that the perimeter of a rectangle is given as
Perimeter = 2(l + b), substituting this, we have
24 = 2(5x + x)
24 = 10x + 2x
24 = 12x
x = 24 / 12
x = 2 inches.
Since x is the width of the rectangle, and it's 2 inches, we use it to find the length of the sign.
l = 5 * 2
l = 10 inches.
Then, we are asked to find the area of the sign. Area of a rectangle is given as
A = l * b, so if we substitute, we have
Area = 10 * 2
Area = 20 square inches
