Answer:

not. sure..

u can correct if there is a mistake.. tnx

Step-by-step explanation:

1.12(2)+6

=24+6

=30

2.6(3)-2(3)(5)+5

=18-2(15)-5

=18-30-5

=18-25

=7

3. 7+2(7-10)

=7+2(-3)

=7-6

=1

Answer:

11. 12a + 6 ; if a = 2

12(2) + 6 = 30

12. 6a - 2ab + 5 ; when a = 3 and b = 5

6(3) - 2(3)(5) + 5 = -17

13. x + 2(x - 10) ; if x = 7

7 + 2(7 - 10) = 1

14. 12b (b + 2) ; if b = 2

12(2) (2 + 2) = 96

15. (30b + 12) + y ; when b = 5 and y = 7

(30(5) + 12) + 7 = 169

Step-by-step explanation:

11. 12a + 6

12(2) + 6

24 + 6 = 30

12. 6a - 2ab + 5

6(3) - 2(3)(5) + 5

18 - 30 + 5 = -17 (if MDAS rule will be followed) and -7 (if not)

13. x + 2(x - 10)

7 + 2(7 - 10)

7 + 2(-3)

7 + -6 = 1

14. 12b (b + 2)

12(2) (2 + 2)

24 (4) = 96

15. (30b + 12) + y

(30(5) + 12) + 7

(150 + 12) + 7

162 + 7 = 169
