Answer:
(2, - 3 )
Step-by-step explanation:
Given the 2 equations
2x - 3y = 13 → (1)
x + 2y = - 4 → (2)
Rearrange (2) expressing x in terms of y by subtracting 2y from both sides
x = - 4 - 2y → (3)
Substitute x = - 4 - 2y into (1)
2(- 4 - 2y) - 3y = 13 ← distribute and simplify left side
- 8 - 4y - 3y = 13
- 8 - 7y = 13 ( add 8 to both sides )
- 7y = 21 ( divide both sides by - 7 )
y = - 3
Substitute y = - 3 into (3) for corresponding value of x
x = - 4 - 2(- 3) = - 4 + 6 = 2
Solution is (2, - 3 )
Find the surface area of a cube by squaring the length of one side and multiplying the result by 6.
Example: The surface area of a cube with side length 3 is "6 x (3 x 3) = 54".

Step-by-step explanation:
Solution :
1. A chart monitoring the object counts with some specific characteristic during the time period and/or some of consistent amount area -- c. c - chart
2. A chart which monitors the subgroup variations within the range of subgroups -- a. R chart
3. The chart monitoring the variation of within subgroup to that of the standard deviations of the subgroups -- d. s chart
4. The chart which monitors the objects' proportion from the sample size of n which does or does not have any particular characteristics -- g. p chart
5. The chart monitoring the averages between the subgroup of the quantitative characteristic keys -- b. x-"bar" chart

PERIMETER:
To find the perimeter of the trapezoid, simply add all sides together.
15 + 5 + 9 + 5 = 34
The perimeter is ![\boxed{ \bf 34~units.}](https://tex.z-dn.net/?f=%5Cboxed%7B%20%5Cbf%2034~units.%7D)

A =
4(9 + 15)
A =
4(24)
A = 2(24)
A = 48
The area of the trapezoid is ![\boxed{ \bf 48~units^2}](https://tex.z-dn.net/?f=%5Cboxed%7B%20%5Cbf%2048~units%5E2%7D)
