Answer 1

Explanation:

open the brackets by multiplying 4 and 28 =112

18+112= 130

Answer 2

Use the distributive property and expand 28, then distribute the 4 to 20 and the 4 to 8. Then you have 18 + 80 + 32. Use commutative property to reverse the order of 32 and 80 so that 18 and 32 are friendly numbers to add.
