Which description is correct for the polynomial 4x² + 3x +5?

antoniya [11.8K]

Answer:

A. Quadratic trinomial

Step-by-step explanation:

You can easily eliminate B and C because trinomial means there are three terms. B has monomial (one term) and C has binomial (two terms).

Now you have A and D. D is cubic which means the first term (4x²) would have to be cubed (4x³). Quadratic means it is squared.

A survey indicated that 2 out of 4 doctors used brand X aspirin. If 1000 doctors used brand X, how many doctors were surveyed? P

Ratling [72]

We can set this up as a proportion.

Since 2 is proportional to 1000, then 4 is proportional to "doctors surveyed".

$\frac{2}{4} = \frac{1000}{d}$ where d is the doctors surveyed.

Cross multiply.

2d = 4000
d=2000

2000 doctors were surveyed.
