Step-by-step explanation:
Answer:
Acute and Equilateral
Step-by-step explanation:
The little dashes on the sides indicate congruent sides
Each side has a singular dash meaning that all the sides are congruent. If all the sides are congruent then all of the angles are congruent
The angles in an equilateral triangle are 60
An acute triangle angles are all less than 90
All of the angles in a equilateral triangle are less than 90 therefore this is an equilateral acute triangle
The correct answer is: [A]: " 4x³ + x² + x + 3 " .

Explanation:
______________________________________________________
(3x³ + 2x² + 2x + 1) + (x³ − x² −<span> x + 2) =
</span>↔ (x³ − x² − x + 2) + (3x³ + 2x² + 2x + 1) =
<span>
</span>(x³ − x² − x + 2) + (3x³ + 2x² + 2x + 1) =
x³ − x² − x + 2 + 3x³ + 2x² + 2x + 1 ;
<span>
Combine the "like terms" ;
x</span>³ + 3x³ = + 4x³ ;
−x² + 2x² = + x² ;
− x + 2x = + x ;
+ 2 + 1 = + 3 ;

And rewrite:

→ " 4x³ + x² + x + 3 " ;
→ which is: "Answer choice: [A]: " 4x³ + x² + x + 3 " .
