C: 2x(3x+4)
D: 2x(3x+4)+(3x+4)

Answer 1

Distribute for these

Answer 2

Oh I see

Answer 3

For the top you need to use the FOIL method

Answer 4

When I use the foil method I get some answer starting w/ 6x?

Answer 5

Yes 6x^2

Answer 6

noo it has to be one of the listed answers. i can't figure out how to get one of them.

Answer 7

Yeah I've been looking, none of them seem correct

Answer 8

:(

Answer 9

wait!!!!!

Answer 10

Your adding the terms I was multiplying in the MC answers

Answer 11

So what did you get when you foiled out that expression? (2x+1)(3x+4)

Answer 12

6x^2+?

Answer 13

no 6x^2+11x+4

Answer 14

Yes good

Answer 15

Now what answer will give you 6x^2

Answer 16

You can eliminate some right off the bat

Answer 17

Does 2x times 2x give you 6x^2?

Answer 18

c???

Answer 19

That is not right because it won't give you 11x

Answer 20

So not A or C is there an e in the problem?

Answer 21

that was a typo, i meant to put a 3

Answer 22

Oh okay!

Answer 23

So it's b or d

Answer 24

Let's just look let's expand B 2x(3x+4)+3(3x+4) so multiply the 2x but the inside parenthesis and the 3 inside the other parenthesis than add like terms

Answer 25

Let me know what you get when you do that

Answer 26

i'm so confused :((( i calculated D w/ wolfram alpha and it gets the same result as the initial problem put into a foil calculator so is it d?

Answer 27

It is D do you need me to explain why it is D?

Answer 28

yes pls

Answer 29

2x(3x+4)+(3x+4) first we are going to distribute the 2x into the the parenthesis so we do 2x times 3x=6x^2 than the second part 2x times 4 which equals 8x and than we are adding everything now so we have 6x^2+8x+3x+4 so now we just add like terms so our x's are the same terms so we can add 8x+3x=11x so we get back to 6x^2+11x+4
