Evaluate 5x² – 3x+2 for x = -3,
A. -52
B. 28
C. 38
D. 56

56

Step-by-step explanation:

We just plugin -3 for all the x values. We get: 5(-3)^2+-3(-3)+2.

(-3)^2=9, -3(-3)= 9 because it is the same as (-3)^2.

We get 5(9)+9+2=>45+11=>56=>D.

And no, that was not meant be an emoji.

:D

D

Step-by-step explanation:

Substitute -3 in place of all the X’s. The equation soon becomes 5(-3)^2 - 3(-3) + 2. Then, PEMDAS! There is nothing to solve in parentheses so you move on to exponents! The power of two into -3 will give you 9. It changes from a negative to a positive because a negative times a negative equals a positive. After that, you then multiply the five into the 9 which will give you 45. Moving on to the second half of the equations, it’s - 3(-3). Just like before, a negative times a negative equals a positive. This too is 9. Then, + 2. When 45 + 9 + 2 is there, you do the simple math and obtain the answer 56! :D Hope this helps!

im sorry but no. i just need to answer for 50 poonts oof

think the answer would beb
