a, c and e are equivalent.
Polynomial is an algebraic expression that consists of variables and coefficients. Variable are called unknown. We can apply arithmetic operations such as addition, subtraction, etc. But not divisible by variable.
Given
a. (3.4a – 1.7b) + (2.5a – 3.9b)
b. (2.5a + 1.6b) + (3.4a + 4b)
c. (–3.9b + a) + (–1.7b + 4.9a)
d. (–0.4b) + (6b – 5.9a)
e. (5.9a – 5.6b)
The addition of the given polynomial.
Add a term with a and b term with b.
a. (3.4a – 1.7b) + (2.5a – 3.9b)
3.4a - 1.7b + 2.5a -3.9b
5.9a - 5.6b
b. (2.5a + 1.6b) + (3.4a + 4b)
2.5a + 1.6b + 3.4a + 4b
5.9a + 4.6b
c. (–3.9b + a) + (–1.7b + 4.9a)
-3.9b + a - 1.7b + 4.9a
5.9a - 5.6b
d. (–0.4b) + (6b – 5.9a)
-0.4b + 6b - 5.9a
-5.9a + 5.6b
e. (5.9a – 5.6b)
5.9a - 5.6b
Thus, a, c, and e are equivalent.
