Answer:

A. Scalene

C. Acute

Step-by-step explanation:

This could be a scalene due to its unequal sides.

This could also be an acute due to the angles being less than 90 degrees.

Right triangles have one angle that measures exactly 90 degrees, you'll see this when there is a square on an angles of a triangle.

Isosceles triangles have 2 equal sides, or 2 equal degrees.

Equilateral triangles has 3 equal sides, and 3 equal degrees(60 degrees).

Obtuse triangles has 1 angles greater than 90 and the other 2 angles are less than 90 degrees.

1/a^2-3a+2 + 1/a^2-5a+6 + 2/a^2-8a+15

Inessa [10]

Answer:

$\frac{4+16a^3+23a^3}{a^2}$

Step-by-step explanation:

Given

$1/a^2-3a+2 + 1/a^2-5a+6 + 2/a^2-8a+15$

Required

Simplify

$1/a^2-3a+2 + 1/a^2-5a+6 + 2/a^2-8a+15$

Collect Like Terms

$1/a^2 + 1/a^2 + 2/a^2-3a-5a-8a+2+6+15$

$1/a^2 + 1/a^2 + 2/a^2-16a+23$

Add Fractions:

$\frac{1+1+2}{a^2} + 16a + 23$

$\frac{4}{a^2} + 16a + 23$

This can be further expressed as:

$\frac{4+16a^3+23a^3}{a^2}$
