What does the expression 5(x+3) mean? 1. the product of five and the sum of x and three2. the sum of five times x and three3. the sum of five and the product of x and three4. the product of five added to x and three

Number 1 would be the correct answer :)

You did not list the choices. however, if you plug in a choice you can figure this out. if the coices were (1,2) and (1/3,1) we could plug in one at a time.

y = 2x + 1/3
2 = 2 (1) + 1/3
2 = 2 1/3
this is not right so it is not an answer.

check other one
y = 2x + 1/3
1 = 2 (1/3) + 1/3
1 = 2/3 + 1/3
1 = 1
this would be a solution since true. hope this helps
