What is the value of 5 (y + 3) - 3x² when x=4 and y=2?

OA) - 23

OB) - 10

OC) 10

OD) 23

-23

Step-by-step explanation:

Plug in the x and the y into the equation:

5 ((2) + 3) - 3 (4) ^2

On the left side of the equation distribute the 5 to the 2 and the three to get:

(10+15) - 3 (4) ^2

which would give us

(25) - 3 (4) ^2

lets solve the other side now

4^2 is 16 and multiply that by 3 to get 48

so it should look like this:

25-48

=-23
