Foundational concepts Unit Test part 1.

What is the simplified form?
6c^2+2.5d-d+2c^2-3d

Please help i don't understand

Well, it looks like you have a bit of a mash-up of terms there. Let's see if we can simplify it!

First, let's group similar terms together. We have 6c^2 and 2c^2, so together they combine to give us 8c^2.

Next, we have 2.5d, -d, and -3d. When we add them all up, we get -1.5d.

Combining these results, we have 8c^2 - 1.5d as the simplified form.

Hope that helps! Keep up the good work, math can be a bit tricky sometimes, but you got this!

To simplify the expression 6c^2 + 2.5d - d + 2c^2 - 3d, you can combine like terms.

First, combine the terms with the same variable, c^2:
6c^2 + 2c^2 = (6 + 2)c^2 = 8c^2

Next, combine the terms with the same variable, d:
2.5d - d - 3d = (2.5 - 1 - 3)d = -1.5d

So, the simplified form of the expression is 8c^2 - 1.5d.

To simplify the given expression: 6c^2 + 2.5d - d + 2c^2 - 3d, we need to combine like terms. Like terms are terms that have the same variable(s) raised to the same power(s).

First, let's group the like terms together:

(6c^2 + 2c^2) + (2.5d - d - 3d)

Now, let's simplify each group of like terms separately:

6c^2 + 2c^2 = (6 + 2)c^2 = 8c^2

2.5d - d - 3d = -0.5d - 3d = (-0.5 - 3)d = -3.5d

Putting it all together, the simplified form of the expression 6c^2 + 2.5d - d + 2c^2 - 3d is:

8c^2 - 3.5d
