phi · Answer

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

phi · Answer

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

anonymous · Answer

ten

anonymous · Answer

each

phi · Answer

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

uri · Answer

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