Do not solve! Re-write the expression using Distributive property
4(8n + 2)

32n + 8

Step-by-step explanation:

Multiply 4 and 8 and get 32, drop n. Same with the 2.

4 ⋅ 8n + 4 ⋅ 2

Step-by-step explanation:

256π units²   (answer b)

step-by-step explanation:

the formula for the surface area of a sphere of radius r

is             a = 4πr²

and so, if r = 8 units, then the surface area is:

a = 4π(8 units)² = 256π units²   (answer b)

step-by-step explanation :

we know that

the measurement of the outer angle is the semi-difference of the arcs which comprises

in this problem

m< xzy is the outer angle

substitute the values

the measure of angle xoy is equal to

> by central angle

substitute the value
