Answer:
-m^3 - 3m^2 +2m -4
Step-by-step explanation:
(m^3-3m^2+m-1)-(2m^3-m+3)
Distribute the minus sign
(m^3-3m^2+m-1)-2m^3+m-3
I like to line them up vertically
m^3-3m^2+m-1
-2m^3 +m-3
--------------------------
-m^3 - 3m^2 +2m -4
Answer:
153.94 cm
Step-by-step explanation:
d=2r (need radius (r) to solve for the area)
14=2r
r=7
A=πr²
A=π(7)²
A=π49
A=153.94
You need to add all of these values together. This is 2 + 9 + 4 which gives 15
There are 180° in a triangle. Divide this by 15.
180/15 = 12
Then multiply this by the largest in the ratio; which is 9.
This is 12 x 9 which = 108°.
The largest angle is therefore 108°.
For reference, the ratio in degrees would look like this:
24:108:48, which adds up to 180°.
