6(a+2b+3c) what is the answer

6a + 12b + 18c

Step-by-step explanation:

6(a + 2b + 3c)

We expand the expression

6a + 12b + 18c

6a + 12b + 18c

Step-by-step explanation:

6(a+2b+3c)

First distribute the 6. This means you need to multiply the 6 by everything inside the parenthesis.

(6 x a) + (6 x 2b)  + (6 x 3c)

Than simplify

6a + 12b + 18c

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18

answer:

your answer is: c. 196 7/8 in^3.
