Which description is correct for the polynomial -5x^2 - 3x + 3
A.) Quartic binomial
B.) Quadratic trinomial
C.) Cubic binomial
D.) Quadratic binomial

Solution:

Given polynomial is:

We have to find the correct description for polynomial

From given,

The highest degree is 2

Thus the degree of this polynomial is 2

Here, the number of terms are three

Thus the polynomial is quadratic trinomial

Quadratic trinomial is a polynomial expression of the form:

Thus the given is quadratic trinomial

total amount to be paid = $19.5

step-by-step explanation:

given ,

original price = $25.99

discount = 25%

discount amount = 25% of original price

discount amount = 25/100   * 25.99

discount amount = $6.49

hence , the total amount to be paid = original price - discount amount

                                                            = $25.99 - $6.49

                                                            =$19.5

total amount to be paid = $19.5

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
