Combine like terms to simplify the expression:<br> 1.17-0.07a+(-3.92a)
Pachacha [2.7K]

After combining like terms and simplifying 1.17-0.07a+(-3.92a) we get 1.17-3.99a

Step-by-step explanation:

We need to combine like terms to simplify the expression:

1.17-0.07a+(-3.92a)

Like terms: The terms are like when they have same variable and same exponent.

Solving:

1.17-0.07a+(-3.92a)\\=1.17-0.07a-3.92a\\=1.17+(-0.07a-3.92a)\\=1.17+(-3.99a)\\=1.17-3.99a

So, After combining like terms and simplifying 1.17-0.07a+(-3.92a) we get 1.17-3.99a

Please help. Determine whether mn is parallel to kl. And why it is parallel. Will reward 20 points
satela [25.4K]
It is not parallel. The fact that there is more space between the lines on one side than the other (mk is shorter than nL) shows that the lines must be angled differently, and thus, would eventually intersect.
