Simplify.

lubasha [3.4K]

<span>(-1/2)(4)(-2)(7y)(-1)

Just start multiplying!

-1/2 * 4 = -2
-2 * -2 = 4
4 * 7y = 28y
28y * -1 = -28y

Since that's not an option I suspect you're missing an x.</span>

Find the GCF of 14a5 and 22a3

miskamm [114]

I am assuming that you mean $14 a^{5}$ and $22 a^{3}$

Now, let's look for common factors. The first one is $a^{3}$ After we take that out, we are left with 14 and 22. We can take a 2 out of both of these, so the greatest common factors is $2a^{3}$
