## motorcrossteamD21 3 years ago PLEASE HELP ME! 2. 6y5 – 9y5 –3y10 15y5 –54y5 –3y5 Write the polynomial in standard form. Then name the polynomial based on its degree and number of terms. 3. 2 – 11x2 – 8x + 6x2 –5x2 – 8x + 2; quadratic trinomial –5x2 – 8x; quadratic binomial –6x2 – 8x – 2; cubic polynomial 6x2 – 8x + 2; cubic trinomial

Looks like you've posted an entire assignment tonight. :P

Not even close! I have 22 more questions I need help with on this same assignment as well! Haha, I'm in a real pickle.

2. Look for which term in common, then sub/add the rest! ( exactly your previous post)

4. A biologist studied the populations of white-sided jackrabbits and black-tailed jackrabbits over a 5-year period. The biologist modeled the populations, in thousands, with the following polynomials where x is time, in years. White-sided jackrabbits: 5.5x2 – 9.2x + 6.9 Black-tailed jackrabbits: 5.5x2 + 9.9x + 1.3 What polynomial models the total number of white-sided and black-tailed jackrabbits? 11x2 + 0.7x + 8.2 11x2 – 0.7x + 8.2 11x2 – 0.7x – 8.2 –11x2 + 0.7x – 8.2

6. Chlorophyll

Just ADD the same terms together!

7. universitysucks

These are very simple. With the examples I gave, you should be able to try adding the two trinomials together...

8. motorcrossteamD21

11x2 + 0.7x + 8.2?

9. universitysucks

You got it!

A family is having a pool built in their backyard. If their yard is rectangular and measures 7x by 6x and the pool is circular with a radius of 2x how much of the yard will be left over after the pool is built? 38x2 42x2 – 4pix2 42x2 – 2pix2 38pix2
