Step-by-step explanation:
The question is incomplete as the figure of the 3 triangles is not given.
However, I'll give a general tip on how to identify the types of triangles.
1. Right-angled
When one of the three angles of the triangle is 90 degrees, then that triangle is a right-angled triangle
2. Acute triangle
When all the three angles of the triangle are less than 90 degrees, then that triangle is an acute triangle
3. Obtuse triangle
When one of the three angles of the triangle is greater than 90 degrees, then that triangle is an obtuse triangle.

Answer:
3(x + 2)
Step-by-step explanation:

Substitute (-1)3-(-1)+(-1)0
multiply (-3)+1+0
simplify. -2
Final Answer: -2
It's 6!
When you multiply both the numerator and denominator by the same number, you will have an equivalent to the fraction you started with because the new fraction can be reduced to the original fraction.
2/3 = 4/6 = 6/9 = 8/12 = 10/15 = 12/15 etc.
.020 because it is 2 spots behind the decimal
