Answer/Step-by-step explanation:
A. [tex] 4b + 3b [/tex]
Using b = 2
[tex] 4(2) + 3(2) = 8 + 6 = 14 [/tex]
Using b = 4
[tex] 4(4) + 3(4) = 16 + 12 = 28 [/tex]
Using b = 6
[tex] 4(6) + 3(6) = 24 + 18 = 42 [/tex]
Using b = 8
[tex] 4(8) + 3(8) = 32 + 24 = 56 [/tex]
Using b = 10
[tex] 4(10) + 3(10) = 40 + 30 = 70 [/tex]
Using b = 2
[tex] 4(12) + 3(12) = 48 + 36 = 84 [/tex]
B. [tex] 3(x - 2) [/tex]
Using x = 3
[tex] 3(3 - 2) = 3(1) = 3 [/tex]
Using x = 5
[tex] 3(5 - 2) = 3(3) = 9 [/tex]
Using x = 7
[tex] 3(7 - 2) = 3(5) = 15 [/tex]
Using x = 9
[tex] 3(9 - 2) = 3(7) = 21 [/tex]
Using x = 11
[tex] 3(11 - 2) = 3(9) = 27 [/tex]
Using x = 13
[tex] 3(13 - 2) = 3(11) = 33 [/tex]
C. [tex] 5(4a - 1) [/tex]
Using a = 2
[tex] 5(4(2) - 1) = 5(8 - 1) = 5(7) = 35 [/tex]
Using a = 3
[tex] 5(4(3) - 1) = 5(12 - 1) = 5(11) = 55 [/tex]
Using a = 4
[tex] 5(4(4) - 1) = 5(16 - 1) = 5(15) = 75 [/tex]
Using a = 5
[tex] 5(4(5) - 1) = 5(20 - 1) = 5(19) = 95 [/tex]
Using a = 6
[tex] 5(4(6) - 1) = 5(24 - 1) = 5(23) = 115 [/tex]
Using a = 7
[tex] 5(4(7) - 1) = 5(28 - 1) = 5(27) = 135 [/tex]
D. [tex] 6y - 2y + 4 [/tex]
Using y = 2
[tex] 6(2) - 2(2) + 4 = 12 - 4 + 4 = 12 [/tex]
Using y = 3
[tex] 6(3) - 2(3) + 4 = 18 - 6 + 4 = 18 - 2 = 16 [/tex]
Using y = 5
[tex] 6(5) - 2(5) + 4 = 30 - 10 + 4 = 30 - 6 = 24 [/tex]
Using y = 10
[tex] 6(10) - 2(10) + 4 = 60 - 20 + 4 = 60 - 16 = 44 [/tex]
Using y = 8
[tex] 6(8) - 2(8) + 4 = 48 - 16 + 4 = 48 - 12 = 36 [/tex]
Using y = 6
[tex] 6(6) - 2(6) + 4 = 36 - 12 + 4 = 36 - 8 = 28 [/tex]
