Question

PLZZZZZ HELLLPPP! The function a represents the cost of manufacturing product A, in hundreds of dollars, and the function b represents the cost of manufacturing product B, in hundreds of dollars.

Find the expression that describes the total cost of manufacturing both products, a(t) + b(t).

Answer 1

Your answer is 7t2-3t+6

Answer 2

The required expression is
`7t^2+3t+6`.

Explanation:

The function a(t) represents the cost of manufacturing product A, in hundreds of dollars, and the function b(t) represents the cost of manufacturing product B, in hundreds of dollars.

`a(t)=5t+2`

`b(t)=7t^2-2t+4`

The total cost of manufacturing both products is

`a(t)+b(t)=5t+2+7t^2-2t+4`

Combine like terms.

`a(t)+b(t)=7t^2+(5t-2t)+(2+4)`

`a(t)+b(t)=7t^2+3t+6`

Therefore the required expression is
`7t^2+3t+6`.
