Jillian baked 2 batches of cupcakes in 1/4 of an hour. How long did it take her to bake one batch?
Nadya [2.5K]

2 batches:1/4 which is 25 min.

so 1 batch would be half of that.

So just divide 25 by 2, which would get you 12.5

12 minutes, and 30 seconds.

Hope this helped~

Factor the expression. 35g^2 – 2gh – 24h^2
stiks02 [169]

Option C: (7 g-6 h)(5 g+4 h) is the correct answer.

Explanation:

The given expression is 35 g^{2}-2 g h-24 h^{2}

We need to determine the factor of the expression.

Now, let us break the given expression into two groups.

Hence, we get,

35 g^{2}+28 g h-30 g h-24 h^{2}

Simplifying, we get,

\left(35 g^{2}+28 g h\right)+\left(-30 g h-24 h^{2}\right)

Let us factor out 7g from the term \left(35 g^{2}+28 g h\right)

Hence, we have,

7 g(5 g+4 h)+\left(-30 g h-24 h^{2}\right)

Similarly, let us factor out -6h from the term \left(-30 g h-24 h^{2}\right)

Thus, we have,

7 g(5 g+4 h)-6 h(5 g+4 h)

Now, we shall factor out the term 5g+4h , we get,

(7 g-6 h)(5 g+4 h)

Thus, the factorization of the given expression is (7 g-6 h)(5 g+4 h)

Therefore, Option C is the correct answer.

What would this be using a positive exponent?
tatuchka [14]

1 / 9^4 and 1 / 6^3

This is because in order to make a negative exponent into a postive exponent, you need to make it into a fraction, 1 as the top number, and the negative exponent as a postive one.

For example, 6^-3 becomes 1 / 6^3.

I hope I helped.
