Answer :
a, c and e are equivalent.
Polynomial
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)
To find
The addition of the given polynomial.
How to find it?
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.
