Answer:
Scalene
Step-by-step explanation:
Because all triangular angles add up to 180 degrees.
10+20=30
180-30=150
None of those angles are the same.
You can solve this in two ways.
1. Graphical. Plot the graph for x between -5 and 1 (see attachement).
The vertex of the graph is the peak of the curve, which has the coordinates x=-2, y=-9.
2. Analytical. Calculate the derivative of the function f(x)

Solve the equation:

will give the solution x=-2.
Replace x=-2 in the f(x) function and you'll get the value of y:

You get the same answer: x=-2, y=-9
So the answer is

Answer:
5/6
Step-by-step explanation:
Find the lowest common denominator between the 10 and 12.
10 and 12 have the lowest common denominator of 2
10/2=5
12/2=6
So 5/6 is the lowest term of 10/12
