It is very simple, <span>|2x + 4| > 14, we have 2x+4>14 or -(2x+4) >14 (absolute value definition) so 2x> 14-4, x>10/2=5 or -2x>14+4, -x>18/2=9, implies x< - 9
the solution is x>5, or x< -9, so the answer is </span>number line with open circles on _9 and 5, shading going in the opposite directions.
Length = 2x+4
Step-by-step explanation:
P=2W+2L
14x+8 =2(5x)+2L
14x+8=10x+2L
14x+8-10x=2L
4x+8=2L
(4x+8)/2=L
<u>2x+4=L</u>
In this case, you can multiply both sides by 4 to get rid of the 1/4 real quick.
4[1/4(8x+16=4x]
8x+16=16x
8x=16
x=2

What's the question?
Step-by-step explanation:
Answer:
$344.04
Step-by-step explanation:
The markdown multiplies the price by (1 -40%) = 0.60.
The tax multiplies the price by (1 +10%) = 1.10.
The two factors applied to the price make the final price be ...
$521.28·0.60·1.10 = $344.04
The total cost of the surfboard was $344.04.
