Best Answer

Yes.

In algebra, as the multiplication symbol (×) looks very much like an x, it is not written and any two items written next to each other are multiplied together. With 8n this means 8 times n, and n is used to represent a number; thus 8n does indeed mean multiply a number by 8.

We'll use "n" to represent "number." First, "eight times a number" means the number is multiplied by eight. 8n Then, seven is added to 8n. 8n + 7 Also, you can display it like this if it helps: (8 x n) + 7

x divided by8

48divided by8 = 6

let n = number; then 8n squared = 96n and thus 8n = 96 and n = 12

8n + 3 = -29 8n = -32 n = -4

In algebra, 8n means to multiply n and 8. (8xN)

8n

8n - 15 = 57 (add 15 to both sides)8n - 15 + 15 = 57 + 158n = 72 (divide both sides by 8)8n/8 = 72/8n = 9

let n = number; then 8n squared = 96n and thus 8n = 96 and n = 12

13

712 divided by8 with all the work = 89

8n + 3 = -29 8n = -32 n = -4

Assuming the number is n; then: 2n + (6n + 5) = 8n + 5 That means five added to eight times the number
