Question

Help please. @alexiselizabeth

Answer 1

Do you know how to distribute?

Answer 2

no :/

Answer 3

Distribution is multiplying all the terms on the inside of the parentheses by the term that is in front of it.

Answer 4

i got B 10y

Answer 5

No.

Answer 6

How did you get 10y?

Answer 7

\[\overbrace{-3(-4y + 3) + 7y}^{Your~equation.}\]
Distributing is a simple concept.
\[\overbrace{-3(-4y}^{\text{Times these two terms together}} + 3) + 7y\]
So:
\[-3 \times -4y = 12y\]

\[\overbrace{-3(-4y + 3) + 7y}^{\text{Our old equation}}\]
\[\overbrace{-3~12y (+ 3) + 7y}^{\text{Our new equation}}\]

Do the same for what is inside the leftover soft brackets.
\[-3 * 3 = -9\]

\[\overbrace{12y -9 + 7y}^{\text{Our new equation}}\]

Simplify aka combine the like terms.

Answer 8

Sir, as someone that has been distributing for years, that was quite confusing.

Answer 9

\[a(b+c)+d=a \times b + a \times c +d\]

Answer 10

Yeah, explaining distribution in text format is a pain. I am not that good with \(\LaTeX\). I am honestly trying to find a way to explain the method to him. (Searching Khan Academy for a video that explain distribution but I cannot find it.)

Answer 11

–3(–4y + 3) + 7y

12y -9 +7y

19y-9??? am i right

Answer 12

You understood my work? LOL, impressive. Yes you are correct. :-)

Answer 13

somewhat lol thank you!! :D

Answer 14

can you help me with this one

Answer 15

I would recommend you search on Khan Academy or YouTube for more help on distribution, as it a necessary for higher mathematics.

Yeah, I can help just a second. :-)

Answer 16

okay thank you. :)

Answer 17

"The product of a number and 5 is no more than 8."
"The product of a number and 5" is written as: \(5n\).
"No more" allows it to be from the number 8 and below, to represent this we write it as:
\[ 5n \le 8 \]

\(\le\) means less than or equal to.

Answer 18

Do you understand?

Answer 19

ohh gotcha, yes okay so it will be C.

Answer 20

Yes, you are correct. :-)

Answer 21

okay thank you! :D

Answer 22

No problem, if you need more help explaining the concept of something, tag me and I will see if I can assist you. :-)

Answer 23

sorry i was in the shower than i went to sleep
