If you are starting off with zero then your end product would be zero
a)8x-4(2x-5)= -8
b) parallel lines(they never touch)
and for A all you have to do is solve it like normal and you will end up with a impossible solution
The slope of the linear equation, 
, is: 
<em><u>Recall:</u></em>
- A linear equation in slope-intercept form is given as: <em>y = mx + b.</em>
- "m" is the slope.
- "b" is the y-intercept.
Thus, given the linear equation:
,
C represents y
m represents x
represents the slope (m)
22.5 represents b.
Therefore, the slope of the linear equation, , is:

I don't know the area of a parallelogram off the top of my head but you can use the area of the rectangle and the area of the triangle and add those. The area of the triangle is 1/2*base*height and use the pythagorean theorem to find the base. 3² + b² = 5²; 9 + b² = 25; b² = 16; b = 4. The area of the triangle is 1/2*4*3 or 6 in. Since there are two of them, the total area of the triangles are 12 in. The area of the rectangle is length*width or (12 - 4) * 3 which is 8 * 3 or 24in. Add these areas together to get 36in total
Answer: The z-score = 2.46
Step-by-step explanation:
Given: sample size : n= 10
Population mean : 
population standard deviation : 
Sample mean : 
Formula to calculate z :
Substitute all values, we get
Hence, the z-score = 2.46
