10x^4 - 4x + 6

Explanation:

Just take the width of the rectangle and multiply each number by 2, including the exponent.

Answer & Step-by-step explanation:

We can solve this problem by multiplying the the expression by 2 one term at a time just like it is shown in the diagram. Your exponent will remain the same.

(5x² * 2) + (-2x * 2) + (3 * 2)

10x² - 4x + 6

So, once you multiply th terms togehter, your final answer will (10x²-4x+6)

it is a. 4.2 because 7.6-3.4 gets the remaining length of 4.2. i might be wrong but i am pretty sure this is the answer.
