8 * 2 * 10 = 160 * 10 = 1600

In order to evaluate the given function at x = -3, simply replace "x" in the function with -3 and solve.

<em>Multiply -4 and -3 in the function above.</em>

<em>Add 3 on both sides of the equation.</em>


<em>Add 2y on both sides of the equation.</em>


<em>Divide both sides of the equation by -3.</em>


Therefore, at x = -3, the value of y = -5. Hence, f(-3) = -5.
Answer:
f(-3) = -5

Answer:
60
Step-by-step explanation:
The perimeter is the measurement around an object.
So first you multiply the 20 and the 10 by 2.
20 * 2 = 40
10 * 2 = 20
Then, add then up!
40 + 20 = 60
