Let f(x) = x² + 3x
What is f(-1) ?

Need help ASAP

-2

Step-by-step explanation:

f(x) = x² +3x

so f(-1) means f(x= -1) so wherever you see a "x" in your equation you put a "-1"

f(-1) = (-1)² +3*(-1) = 1 -3 = -2

x = 17

step-by-step explanation:

1st step: isolate x.

24 - 3x = -27

-24         -24

-3x   =   -51

2nd step: divide.

-3x     =   -51

  3             3

  x       =     17

hope this

answer: 16

step-by-step explanation: first you would add 6+6 which equals 12 then add 2+2 which equals 4. then add 12 + 4 which is 16.

hope this ^_^
