Answer:
2 and -3
Step-by-step explanation:
2x^2=4x
4x+2x=12
6x=12
how many times does 6 go into 12?
right, 2 times!
x=2
---
2x^2+2x-12=0
x^2+x-6=0
(x+3)(x-2)=0
X=-3 and 2
24 months. 1 year equals 12 months. 12x2=24

12% of 120 is 14.4
Change the percentage into a decimal by dividing over 100:
12 / 100 = 0.12
Multiply:
0.12 × 120 = 14.4
Answer:
Step-by-step explanation:
1x+3x+4x= 128
8x=128
x=128/8
x=16
therefore,
room 1 = 1x
= 1*16=16
room 2 = 3x
=3*16=48
room 3 = 4x
=4*16=64
