Question

Part A: Write an algebraic expression for 8 more than 5 times a number.

Part B: Write a verbal expression for 4(n + 6)

Answer 1

So for part A, we are adding 8 (+8) to 5 times a number. Use x as the variable. How do you write "5 times a number" ?

Answer 2

5 x n.

Answer 3

mhm or just 5n. so then you are adding 8 to the 5n. And that looks like what?

Answer 4

13n

Answer 5

no, we aren't adding anymore n's. it's just 5n and then plus a constant of 8

Answer 6

ohh

Answer 7

5n + 8?

Answer 8

yeah. and then for part B, we have in parentheses the quantity of n plus 6. and there is a 4 in front of the parentheses, so what does that mean?

Answer 9

6n+ 4

Answer 10

no, it's already written as 4(n+6) we just have to write it verbally. When you look at `4(n+6)` how do you read it?

Answer 11

4n +6

Answer 12

i-
yes, but i mean, write it out in words, not as an expression please.

Answer 13

ok, four n plus 6

Answer 14

ok, so you're close, but it's going to be `four times the sum of a number and six` and the reason for this is because the 4 has not been distributed yet, so it's read as `four times` and then the four is going to the parentheses and they say n+6, which means `the sum of a number and 6`

Answer 15

im supposed to write all this in words.

Answer 16

for part B, you write the first thing that is highlighted, yes. For part A, you write the expression that we made.

Answer 17

ok

Answer 18

please close this when you are finished. have a nice day (:
