Answer:

A, B

Step-by-step explanation:

A polynomial is an expression containing two or more algebraic terms. They are often the sum of several terms containing different powers (exponents) of variables and never contains square roots or division by a variable.

In your case, option A contains two terms that with second and first power of x. Therefore, the expression in A is a polynomial. Option B contains three terms that with second, first power of x and coefficient. This is a polynomial too. Option C represents the absolute value of x and doesn't represent a polynomial.

Answer:

$Total\ length = 8\frac{5}{8}\ miles$

Step-by-step explanation:

Given

See attachment for ski trails

Required

Total length of $2\frac{7}{8}$ ski trails

From the attached figure, there are 3 skis with length $2\frac{7}{8}\ miles$

So:

The total length is:

$Total\ length = 3 * 2\frac{7}{8}$

Express fraction as improper fraction

$Total\ length = 3 * \frac{23}{8}$

$Total\ length = \frac{3 *23}{8}$

$Total\ length = \frac{69}{8}$

$Total\ length = 8\frac{5}{8}\ miles$

The area of a rectangle is 30 square root 3750 square inches, and the length is 3 square root 250 inches what is the width of th

Ann [662]

Answer:

$width=10\sqrt{15}\ in$

Step-by-step explanation:

-A rectangle's area is given by:

$A=lw\\\\l=length\\w=width$

Given A= $30\sqrt{3750}$ and $l=3\sqrt{250}$ , we substitute in the formula to solve for the width as follows:

$A=lw\\\\30\sqrt{3750}=3\sqrt{250}\times w\\\\w=\frac{30\sqrt{3750}}{3\sqrt{250}}\\\\w=10\frac{\sqrt{3750}}{\sqrt{250}}\\\\=10\times \sqrt{\frac{3750}{250}}\\\\=10\sqrt{15}\ in$

Hence , the rectangle's width is $10\sqrt{15}\ in$
