Question

Write ( d + 5 ) + ( d + 5 ) + ( d + 5 ) + ( d + 5 ) as an equivalent expression by grouping the like terms

Answer 1

4d+20. Four d’s mean 4d or 4 times d. 5+5+5+5 is 20, so in expression form it would be 4d+20.

Answer 2

Group the d’s together and you would get 4d and then group the 5’s together and you get 20
