Answer:
3.4 - 2.8d + 2.8d - 1.3 = 2.1
Step-by-step explanation:
The given expression is 3.4 -2.8d + 2.8d -1.3
Let's see the definition of like terms.
Like terms are the terms having the same variable and the same exponents.
Examples: -3xy, 2xy and 4y, 5y and -3, 2.
Now let's identify the like terms from the given expression.
3.4 -2.8d + 2.8d -1.3
Here the like terms are -2.8d, +2.8d and 3.4, -1.3
3.4 -2.8d + 2.8d -1.3
= -2.8d + 2.8d + 3.4 - 1.3 [-2.8d + 2.8d = 0] and 3.4 -1.3 = 2.1
= 0 + 2.1
=2.1
The answer is 2.1
