Someone factor x^2+18x+77

1 answer:

5 0

77 is a multiple of 11, as i'm sure you know--the double numbers like 22 and 55, one of the factors are always 11.

77 is factored down into 11 and 7--which, when you add those, luckily equal 18.

(x + 11)(x + 7) is your factorization.

A soup can has a diameter of 4 inches and the height of the can is 7 inches. Desiree needs to design a label for the soup can. A

Hoochie [10]

Answer:

87.96 square inches

Step-by-step explanation:

The soup can is a cylinder, and we can find how many square inches the label will take up by finding the lateral surface area

Use the formula, LA = 2 $\pi$ rh

The diameter is 4 inches, so the radius is 2 inches

Plug in the radius and height into the formula, and solve:

LA = 2 $\pi$ rh

LA = 2 $\pi$ (2)(7)

LA = 28 $\pi$

= 87.96

So, the label will take up approximately 87.96 square inches
