2x + 4 ( -6x + 12) = -84<br><br> What is X?
katrin [286]
2x + 4(-6x + 12) = -84

2x - 24x + 48 = -84

-22x + 48 = -84

-22x = -84 - 48

-22x = -132

x = -132/-22

x = 6

hope this helps, God bless!

GEOMETRY!!!! K' (6,5) is the image of K after a reflection in the line y=2. what are the coordinates of K
frutty [35]

Given:

The coordinates of point K' are (6,5).

K' is the image of K after a reflection in the line y=2.

To find:

The coordinates of point K.

Solution:

Let the coordinates of point K are (a,b).

If a figure is reflected over the line y=2, then

(x,y)\to (x,2(2)-y)

(x,y)\to (x,4-y)

Using this formula, the coordinates of image of K are

K(a,b)\to K'(a,4-b)

The coordinates of point K' are (6,5).

K'(a,4-b)=K'(6,5)

On comparing both sides, we get

a=6\text{ and }4-b=5

a=6\text{ and }-b=5-4

a=6\text{ and }-b=1

a=6\text{ and }b=-1

Therefore, the coordinates of point K are (6,-1).

Approximately how many liters are in 20 gallons 1 L 0.26 gal.
Sergeu [11.5K]

Answer:

77 litres

Step-by-step explanation:

1L = 0.26 gal

0.26 gal = 1L

Divide both sides by 0.26

1 gal = 1 ➗ 0.26

1 gal = 3.85 L

Now multiply both sides by 20

20 gal = 3.85 × 20

20 gallons = 77 litres

I hope this was helpful, please mark as brainliest
