Firlakuza [10]

Answer:

6  "surprise" flavors jellybeans

Step-by-step explanation:

From the information given:

The bag contained a mixture of regular flavored jellybeans and "surprise" jellybeans.

There are 40 jellybeans in the bag.

If 15% of the jellybean were "surprise" flavors.

Then, the number of expected "surprise" jellybeans will be:

= 15% of 40 jellybeans

= (15/100) × 40

(3x^2) (2x^5)<br>use the properties of exponents to simplify​
Solnce55 [7]

Answer:

6x^7.

Step-by-step explanation:

The exponent property for this would be that

x^a * x^b = x^a + b.

So x^2 * x^5 = x^2 + 5 or x^7.

The other part is just multiplying the coefficients 3 and 2, which is 6.

Put these together and you get your answer 6x^7.
