Answer:
(-4a + b – 2c) – (3a + 2b –c)
-4a+b-2c-3a-2b+c
-7a-b-c
Step-by-step explanation:
To find the measure of each angle you add all of the sides
Then, all triangles equal 180
3x + 2x + x = 180
Like terms
6x = 180
/6. /6
X = 30
Now to find the measures of the angles
You plug in the value of x
1st angle =. 3x
3(30)
=90
2nd angle = 2x
2(30)
=60
3 angle =. X
=30

Answer:
13= -14x
Step-by-step explanation:
(4×2)-(4×1x)=(5×1)-(5×2x)
8-4x=5-10x
8+5=-4x-10x
13=-14x
Hopefully this will help
Answer:
Slope in fraction form = 5/2
Slope in decimal form = 2.5
========================================================
Work Shown:
m = (y2-y1)/(x2-x1)
m = (-5-10)/(-2-4)
m = (-15)/(-6)
m = (-3*5)/(-3*2)
m = 5/2 slope in fraction form
m = 2.5 slope in decimal form
-----------------
Explanation:
The first step is the slope formula where (x1,y1) and (x2,y2) are the two points the line goes through.
I used (x1,y1) = (4,10) and (x2,y2) = (-2,-5)
The slope formula basically says "subtract the y values, then subtract the x values in the same order. Then divide the two differences".
Or you can think of it as
slope = rise/run
rise = y2-y1 = change in y
run = x2-x1 = change in x
