<h3>Step-by-step explanation:</h3>

<u>Step</u>                <u>Property</u>

2x+6 = 22       given

2x = 16            addition property of equality (-6 added to both sides)

x = 8                multiplication property of equality (both sides × 1/2)

_____

In general equations are solved by reversing the steps done to the variable. Here, the variable (x) is multiplied by 2 and 6 is added to that product. So, to find x, we undo the addition of 6 (by adding -6, the additive inverse), and undo the multiplication by 2 (by multiplying by 1/2, the multiplicative inverse).

If other functions were performed on the variable in the original equation, their inverse functions would be used, too, as part of the solution process.

Answer:

Not quite sure what you're meant to solve for, but my solution is below.

Step-by-step explanation:

The square root of a value squared is the absolute value of that value, because squaring removes all negatives. Therefore:

\sqrt{(y+2)^2}=c

\mid y+2\mid=c

\mid y\mid =c-2

Hope this helps!

How many sides do 4 hexagons, 1 octagon, and 5 dodecagons have in all?
Vladimir79 [104]
Hexagon = 6 sides = 6 x 4 = 24 

Octagon = 8 sides = 8

Dodecagons = 12 x 5 = 60

24 + 8 + 60 =  92 IN TOTAL

The following data show the prices of different types of outfits at a store: $2, $2, $28, $26, $25, $27, $25, $27, $26, $28, $30
arlik [135]

2, 2, 25, 25, 26, 26, 27, 28, 28, 30

Minimum: 2

Maximum: 30

Median: 26

Lower quartile: 25

Upper quartile: 28

The box plot will have its left tail longer than the right tail because a few exceptionally low prices make the distribution skewed to the left.
