which equivalent expression will be generated by applying the distributive property and combining like terms in the expression 11 + 4(x + 2y + 4)?

27+4x+8y

or

4x+8y+27 ( I can reorder this a few different ways. I don't know what your choices are)

Step-by-step explanation:

11+4(x+2y+4)

We can apply distributive property to the 4(x+2y+4), this will give us 4x+8y+16.

Bring down the 11+ and we have 11+4x+8y+16.

The only like terms we have is 11 and 16.  So reorder using commutative property and get 11+16+4x+8y.

I'm going to simplify the 11+16 part which gives us 27.

In the end we have 27+4x+8y.

Let me line up so it is all nice and neat:

11+4(x+2y+4)

11+4x+8y+16

11+16+4x+8y

27+4x+8y

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)

1. is 4 and 2. is 3

step-by-step explanation:

so if you look at the first one you see that 1 is to 4 and 2 is to 8 and so on, so you can see for every 1 there is a times 4 so if it were 3 then it would be 3*4 and it is 12

for number 2 it is 3 because 1 is to 3 and 2 is to 6 so for every 1 there is 3 so if it were 3 then there would be 3*3 = 9
