ASAP I need to know how to do these

1. idk

write 3x as a difference

x^2+4x-x-4>0

then factor out x from the expression

X x (x+4)-x-4>0

factor the negative sign

X x (x+4)- (x+4)>0

( x+4)x (x-1)>0

aneswer: (-∞ , -4) ( 1, + ∞)

$25

step-by-step explanation:

25 - 4.50 = 20.5

20.5 / 2 = 10.25

10.25 + 10 = 20.25

20.25 - 12.50 = 7.75

therefore the answer is $25 as shown as the first number.

idk
