Answer:

6x²+ 9x- 15

Step-by-step explanation:

To find the area of a rectangle multiply length and width.

3(2x²+ 3x-5)

Use the distributive property to solve.

3(2x²)= 6x²

3(3x)= 9x

3(-5)= -15

The area would be

6x²+ 9x- 15

Nina [5.8K]

Answer:

The correct option is C: the isotope of iodine contains 81 neutrons.

Step-by-step explanation:

The mass (A) of the iodine isotope is given by:

A = Z + N

Where:

Z: is the number of protons

N: is the number of neutrons

For iodine Z= 53, so if A = 134 the number of neutrons is:

N = A - Z = 134 - 53 = 81

Therefore, the correct option is C. The isotope of iodine contains 81 neutrons.

I hope it helps you!
