Express as a trinomial (3x+8) (x+10)
docker41 [41]

Answer:

3x^{2} +38x+80

Step-by-step explanation:

Hello!

A trinomial is a expression consisting of three different terms

To turn this into a trinomial we multiply everything to each other

<u>                     3x                     </u>

3x * x = 3x^{2}

3x * 10 = 30x

<u>                     8                      </u>

8 * x = 8x

8 * 10 = 80

Now we put them all together in an equation

3x^{2} +30x+8x+80

Combine like terms

3x^{2} +38x+80

The answer is 3x^{2} +38x+80

Hope this helps!

Determine whether the sequence is arithmetic or geometric.
Elanso [62]
Sequence 1 is arithmetic because it is being subtracted by 16.

Sequence 2 is geometric because it is being divided by 2.

Arithmetic is when you're adding or subtracted and geometric is when you multiplying or dividing.
