Answer:
<u>10x + 8 species</u>
Step-by-step explanation:
Given :
- New bird species = x
- New species of fish = 4x + 18
- New species of amphibians = 3x + 4
- New reptile species = 2x - 14
Solving :
- Total discovered species = sum of the discovered species
- Total = x + 4x + 18 + 3x + 4 + 2x - 14
- Total = <u>10x + 8 species</u>
Total species: 10x + 8
<h3>
</h3><h3>
Explanation:</h3>
<u>Add the algebraic expressions</u>:
Total species = bird + fish + amphibian + reptile
= (x) + (4x + 18) + (3x + 4) + (2x - 14)
<em>group the variables</em>
= x + 4x + 3x + 2x + 18 + 4 - 14
<em>add/subtract integers</em>
= 10x + 8
