Answer:
X= 1 AND 13
Step-by-step explanation:
x2+14x = -13
by completing the square method
you add the square of half the coefficient of b to both sides
which is (14/2)^2
x^2+14x+(7^2) = -13 +(7^2)
x^2 + 7^2 = -13 + 49
x^2 + 7^2 = 36
(x + 7)^2 = 36
find the square root of both sides
(x+7) = + or - 6
x=7-6 ; 1
or
x= 7+6 ; 13

Answer:
The width of the similar rug is 3 ft
Step-by-step explanation:
Calculate the percentage between the lengths:
3/9 = 1/3 (percentage)
The percentage is fixed for the widths as well which means 1/x = 1/3
x=3
The answer is 4^2=4 x 4= 16
