Answer 4

you should learn the "distributive law"

if you have 10 times ( 2x +3)
that means you have 10 times each thing in side the parens

think of the parens as a package, and you have 10 identical packages

Answer 5

so how many 2 x's do you have and how many 3 's do you have

Answer 6

ten

Answer 7

each

Answer 8

yes, and you write it
10(2x+3) = 10* 2x + 10*3

10*3 is easy, right ?
10 * 2x means 10*2*x
you can simplify the 10*2 part

Answer 9

10(2x+3) = 10* 2x + 10*3
=20x+30

Answer 10
