6c2 + 2.5d – d + 2c2 – 3d
To simplify the expression 6c^2 + 2.5d - d + 2c^2 - 3d, combine like terms:
We have:
6c^2 + 2.5d - d + 2c^2 - 3d
Simplifying the c^2 terms first:
6c^2 + 2c^2 = (6 + 2)c^2 = 8c^2
Now, simplify the d terms:
2.5d - d - 3d = 2.5d - 4d = (2.5 - 4)d = -1.5d
Combining the simplified terms:
8c^2 - 1.5d
Therefore, the simplified expression is 8c^2 - 1.5d.
To simplify the expression 6c2 + 2.5d - d + 2c2 - 3d, you can combine like terms. Like terms have the same variables raised to the same power.
Step 1: Group the terms that have the same variables and exponents:
6c^2 + 2c^2 + 2.5d - d - 3d
Step 2: Combine the like terms:
(6c^2 + 2c^2) + (2.5d - d - 3d)
8c^2 - 1.5d
So, the simplified form of the expression 6c2 + 2.5d - d + 2c2 - 3d is 8c^2 - 1.5d.
To simplify the expression 6c2 + 2.5d - d + 2c2 - 3d, we can combine like terms.
Starting with the terms involving c, we have 6c^2 + 2c^2. To combine these, we add the coefficients, which are 6 and 2, respectively. The result is 8c^2.
Moving on to the terms involving d, we have 2.5d - d - 3d. Again, we add the coefficients: 2.5 + (-1) + (-3). This gives us -1.5d.
Putting it all together, the simplified expression is 8c^2 - 1.5d.
