C) 4(9q-r+3)
because you distribute the 4 to the inside of the parentheses. So, 4 x 9q = 36q, 4 x -r = -4r, 4 x 3 = 12. 36q-4r+12 is your answer when you distribute.

W (n) = n^2-n find w (-3)

Papessa [141]

Answer:

$w(-3) = 12$

Step-by-step explanation:

Plug in -3 for n in the equation:

$w(n) = n^2 - n$

$w(-3) = (-3)^{2} - (-3)$

Simplify. Remember to follow PEMDAS. First, solve the power:

$w (-3) = (-3)^2 - (-3)\\w (-3) = (-3 * -3) - (-3)\\w (-3) = (9) - (-3)$

Next, combine like terms. Note that if there are two negative signs directly next to each other, it becomes a positive sign. Add:

$w(-3) = 9 - (-3)\\w(-3) = 9 + 3\\w(-3) = 12$

Your answer: $w(-3) = 12$
