Question

Plug in b and k into the expression in order to get a final answer9(-4k+8b)b= -9 k=4

Answer 1

we are given the following expression:

`9(-4k+8b)`

we are asked to plug in the following constants, b = -9 and k = 4, to do that, we will replace the values given for b and k in the expression, like this:

`9(-4(4)+8(-9))`

Now we will solve the multiplications inside the parenthesis, like this:

`9(-16-72)`

Now we will solve the operation inside the parenthesis, we get:

`9(-88)`

Now we solve the multiplication:

`9(-88)=-792`

therefore, the final answer after pluging in b and k is -792.
