Step-by-step explanation:

1. 36+12m

2. 180+10s and 10(18+s)

Step-by-step explanation:

1. 12(3 + m) is an example of the distributive property of maths, so both 3 and m would be multiplied by 12:

12(3 + m)

= 36 + 12m

2. (10 x 18) + (10 x s) this is PEMDAS, so first you'd multiply the brackets:

(10 x 18) + (10 x s)

= (180) + (10s)

since 180 and 10s have no common term, you leave it like that

This can be factorised out to form 10(18 + s), so that's a right answer too.

b. x + 1

i'am smart

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
