Answer:
m=-3/4
Step-by-step explanation:
First locate two points that are on solid intersections, (-3, 2) and (1, -1).
<u>y2</u><u>-</u><u>y1</u>
Then use x2-x1' where -1 is y2, 2 is y1, 1 is x2, and -3 is x1.
Plug in numbers, <u>-1-2</u><u> </u>= <u>-</u><u>3</u>
1+3 = 4
-3/4 is m (Slope).
Use the attached figure to guide yourself through the explanation. In the figure:

.
We know that:

Also remmeber that the area of a triangle is:

The hegiht is shown in the figure in red, the base is just the b side.
Using the angle C the area of the triangle is:

Now taking the derivative of the area 2A with respect to t we have:

Replacing with the right values:

yields:
Answer:
I love algebra anyways
The ans is in the picture with the steps how i got it
(hope this helps can i plz have brainlist :D hehe)
Step-by-step explanation:
2c^2+5c+4
just add numbers with common variables and exponents
Sum of angles in a triangle=180
70°+60°+(8x+2)°=180°
130°+(8x+2)°=180°
Collect like terms
(8x+2)°=180°-130°
8x+2)°=50°
8x=50-2
8x=48
x=6°
