Evaluate by substituting the given values:

when a = 2, b = 5 and c = -3

3a+6+5a

(a.) 22

(b.) 23

(c.) 24

(d.) 25

It’s 22 here’s why If you do 3 times a which is 3 times 2 is 6 and if you do 5 times a which is 5 times 2 which is 10 and you have 6 and 10 left so you add them 6+10=16 then you have 6 left and finally you do 16 plus 6 which is 22 (A)

to find the total number of combinations, multiply the quantity of each item by each other:

2 pairs of shoes x 3 pairs of shorts = 6 different combinations.
