Simplify to create an equivalent expression.
10+4(-8 q-4)}10+4(−8 q−4)

: -0.3125 + q + 0.5

If our equation is: 10 + 4(-8q - 4)  then we can simplify it in the next way:

first distribute the 4 with the content in the parentheses.

10 + 4(-8q - 4) = 10 -(8*4)q - 4*4 = 10 - 16 -32q = -6 -32q

now dependes on you, i like to put the negative sign outside  a parenthesis:

-(32q + 6)

and this is your simplified equation, just give solve it. HOPES THIS HELPS

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)
