Which of the following equations are true? Select all that apply
Help please I'm doing a test

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.

hope this ! ^w^

the discriminant is 64 + 4*1*12 = 112

this is prime.

step-by-step explanation:

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

y=3n + 1

step-by-step explanation:

this is wrong because it says the second number is one less and i added one instead
