SOMEONE PLS ANSWER THIS QUESTION ITS HARD (the top is an example I don’t understand it)

see below

Step-by-step explanation:

1. 39

2.96

3.85

4.56.

Here's how to do it. so assuming you know one digit multiplication you would want to do something like this

17

x 5

you would start by multiplying 7x5 since those are the first two numbers, then you would get 35, you would carry the 3 to the other side and put the 5 below like this.

3

17

x 5

5

Then after that you would multiply 5x1 since those are the next two numbers and since anything multiplied by a 1 is the same number it would be 5 still, since we have a 3 left over we would add it to the 5 and get 8. Then adding that to the bottom you would get 86.

17

x 5

85

hello from mrbilldoesmath!

answer:

25x^2 + 90x + 84

discussion:

mn(x) = m(n(x)) = m( 5x + 9) =

(5x + 9)^2 + 3 =>

25x^2 + 90x + 9^2 + 3 =

25x^2 + 90x + 84                 (as 9^2 = 9*9 = 81)

which is the second choice
