Answer:
D
x=-4+2√2 or x=-4-2√2
Step-by-step explanation:
3(x+4)²-24
3(x+4)²=24
(x+4)²=24/3
(x+4)²=8
x+4=√8
x+4=±2√2
x=-4+2√2 or x=-4-2√2
Answer:
$119520
Step-by-step explanation:
Given: Purchase price of Diamond ring= $12000
Value of ring increase by 32% each year.
First finding number of year between 2012 and 2040, to know the time period of value appreciation.

Answer:
B. 3x = 6
Step-by-step explanation:
The left side of a hanger is on the left side of the equation, and the right side of a hanger is on the right side of the equation.
There are 3 x's on the left side, so the left side is 3x
The right side shows 6 unit boxes, so the right side is (1 * 6), or 6.
As a result, the equation is 3x = 6, which is B.
Answer:
x=2
Step-by-step explanation:
First of all cross-multiply.
1/2x=1/4
(1) x (4) =1 x 2x
4=2x
After flip the equation.
2x=4
Then divide both sides by 2.
2x/2=4/2
x=2
