Answer:
Step-by-step explanation:
hello :
x²+6x+9 = 20
(x+3)²-20 = 0
(x+3)²-√20 = 0
(x+3-√20)(x+3+√20)=0
x+3-√20=0 or x+3+√20=0
x = -3+√20 or x = -3-√20 answer B
Answer:
18 inches
Step-by-step explanation:
Given: The heights of both cylinders are 48 inches and 32 inches. Diameter of the larger cylinder is 12 inches
To find: diameter of the larger cylinder
Solution:
Height of the larger cylinder (H) = 48 inches
Height of the smaller cylinder (h) = 32 inches
Diameter of the smaller cylinder (d) = 12 inches
Radius of the smaller cylinder (r) = d/2 =12/ 2= 6 inches
As two cylinders are similar, their heights and radii are proportional.
Diameter of the larger cylinder = 2R = 2(9) = 18 inches

Answer: A=L x W
The length is 6 inches more than the width and the area is 72 so 72÷6 = 12
12 is 6 more than 6 so 12 x 6 = 72 the length will be 12 the width is 6 and the area 72 hope this helps
