Which of the following are solutions to the equation below?
Lady_Fox [76]

Answer:

x =4 ±sqrt(5)

Step-by-step explanation:

x2 - 8x + 16 = 5

Complete the square

(x-4)^2 = 5

Take the square root of each side

sqrt((x-4)^2) = ±sqrt(5)

x-4 = ±sqrt(5)

Add 4 to each side

x-4+4 =4 ±sqrt(5)

x =4 ±sqrt(5)

I need help to find the surface area
Diano4ka-milaya [45]

Answer:

125.6 sq ft.

Step-by-step explanation:

To find the Surface Area of the cylinder, we will need to solve for the area of both bases and the rectangle around the cylinder. We can do this by:

------------------------------

Area of bases: (A=\pi r^{2})

A= \pi 2^{2}

A= 4\pi \\A= 12.56

Since we have two bases, we can simply multiply by 2, giving us:

12.56×2= 25.12

-------------------------------

Area of the rectangle: (C=d\pi)

C=4\pi\\C= 12.56\\

12.56×8= 100.48

Add these two together, giving us:

100.48+25.12= 125.6 sq ft.
