<span>4x^2 - 36 = 0 ( Original equation )
4x^2 = 36 ( Add 36 to both sides )
x^2 = 9 ( Divide by 4 on both sides )
x = 3 , -3 ( Take the square root of 9 )
Solution set: { +3 , -3 } answer is x = +3 , x = -3</span>
Answer:
The answer is 135
Step-by-step explanation:
We can use formula: 162...120% since the price was increased by 20% which means it is 120%
So: 162...120%
x.... 100%
120x = 16200 => x = 135
2x+4=7 subtract 4 from both sides
2x=3 divide both sides by 2
x=3/2
x=1.5
Answer:

Answer:
C. -26=x
Step-by-step explanation:
3(3x-2)=5(2x+4)
9x-6=10x+20
9x-10x=20+6
-x=26
-x/-1=26/-1
x= -26
