Question 2
Over a span of just a few years, scientists discovered x new
bird species, 4x + 18 new species of fish,
3x +4 new species of amphibians, and 2x – 14 new reptile
species.
How can you write and simplify an expression that
represents the total number of pecies that were discovered
during this time period?

Answer:
10x + 8 species
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 = 10x + 8 species
Total species: 10x + 8
Explanation:
Add the algebraic expressions:
Total species = bird + fish + amphibian + reptile
= (x) + (4x + 18) + (3x + 4) + (2x - 14)
group the variables
= x + 4x + 3x + 2x + 18 + 4 - 14
add/subtract integers
= 10x + 8
