A. x = -6
6-x-x = 18
6-2x =18
-2x = 12
x = -6
Answer: 5
Step-by-step explanation: The median is the middle number in the data set when the data set is written from least to greatest.
Notice that our data set is already written from least to greatest.
1, 2, 2, 8, 9, 14
Notice that in this data set, there is no middle number directly because 2 and 8 fall directly in the middle. In this situation, we take the average of these two middle numbers and divide their sum by 2.
Since 2 and 8 are the numbers that appear in the middle, we add them.
2 + 8 gives us 10.
Now we divide 10 by 2 to get 5.
So the median of this data set is 5.
Answer:
The length is 9in and the width is 3in
The perimeter is 24in and the area is 27in²
Step-by-step explanation:
To start we have to make 2 equations with the information that gave us the problem
l = length
w = width
w = l - 6in
l = 3w
we replace l in the first equation with (3w)
w = (3w) - 6in
w - 3w = -6in
-2w = -6in
w = -6in / (-2)
w = 3in
now we replace the value of w in the second equation
l = 3w
l = 3 (3in)
l = 9in
Now that we have the length and width we can calculate the perimeter and the area with the following formulas
p = perimeter
a = area
p = 2w + 2h
p = 2(3in) + 2(9in)
p = 6in + 18in
p = 24in
a = w * l
a = 3in * 9in
a = 27in²
2x2-2z4+y2+x2+z4
2*-4*2-2*2*4+3*2- -4*2+2*4
-8*2-4*4+6- -8+8
-16-16+6- -8+8
-32+6- -8+8
-26- -8+8
-18+8
-10
-10 is your answer have a nice day
