Answer:
The value of a = -12.
Step-by-step explanation:
Given that the points are Q( -6, 5) and R ( -2, 3) -
As we know that-
If a line segment AB is with endpoints ( ) and ( ) then the mid points C are-
<em>C = ( , )</em>
Here,
Q( -6, 5) and R ( -2, 3)
then the midpoints C are-
( a/3, 4) = ( , )
We have to find the value of x therefore we need to compare only x coordinate -
<em>a/3 = ( -6 - 2)/2</em>
<em>a/3 = -8/2</em>
<em>a/3 = - 4</em>
<em>a = -12</em>
Hence the value of a = -12.
(2x+3)+(x-6)= 180 [straight angle]
2x+x+3-6=180
3x=183
x=61

Hope this can help.
The slope of the line is the negative 4/3 and y-intercept will be the negative 1.
The correct equation is given below.
−4x − 3y = 3
<h3>What is the linear system?</h3>
A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.
The equation of the line will be
−4x − 3y = 3
Then the equation of a line can be written as
4x + 3y = −3
3y = −4x − 3
y = −(4/3)x − 1
Then the slope of the line is the negative 4/3 and y-intercept will be the negative 1.
The graph is given below.

The answer is 144ft^2
The formula of a trapezoid is a plus b over 2 then times height
A and b are the bases which are 15 and 21
15+21 is 36 and divided by two is 18
18 times the height which is 8
And that gives u the answer
