In a polynomials equation do you add the exponents if they are different
Alexus [3.1K]
You can only add exponents if you are multiplying two of the same variable together. For example,
x^{12} \times x^4 = x^{16}

You take them away if you are dividing.
<span>x^{12} \div x^4 = x^{8}

In a polynomial equation, you can add together two of the same variable if they have the same exponent
</span>3x^4 + 7x^4 = 10x^4

Or you can take them away in a similar fashion,
<span>3x^4 - 7x^4 = -4x^4

But you cannot add two (or more) different exponents,
</span>6+4x+7x^2 = 6+4x+7x^2 (it does not get any simpler)

I hope this has answered your question, if not, leave a comment and I'll update the answer.

Reduce to the lowest terms by canceling -14/9 times -3/7
maksim [4K]

Answer:

2/3

Explanation:

Given the below;

\frac{-14}{9}\times\frac{(-3)}{7}

We can see from the above that 9 is divisible by 3 and that 14 is divisible by 7, let's go ahead and reduce to the lowest term as shown below;

\frac{-14}{9}\times\frac{(-3)}{7}=\frac{-2}{3}\times\frac{(-1)}{1}=\frac{2}{3}

NikAS [45]

Answer:

4512 handshakes

Step-by-step explanation:

We are told in the question, that there are

96 people in the room = 48 couples

Assuming that no husband or wife shakes each others hand but everyone else shakes hands exactly once

This means

48 couples will shake 94 people because they are excluded

This is calculated as

48 × 94 = 4512 handshakes
