Answer:

6p^3 + 29p^2 + 22p - 21

Step-by-step explanation:

You can find the product of the expression using the distributive property. The distributive property multiplies the terms of one parenthesis into each term in the other parenthesis. Simplify the product that results by combining like terms or terms which have the same base and exponent.

(2p+7)(3p^2 +4p-3)

6p^3 + 21p^2 + 8p^2 + 28p -6p - 21

6p^3 + 29p^2 + 22p - 21

Answer:

$174.66\ mi$ or $175\ mi$

Step-by-step explanation:

we know that

Applying the law of cosines

$c^{2}=a^{2}+b^{2}-2(a)(b)cos(C)$

In this problem we have

$a=200\ mi$

$b=30\ mi$

$C=30\°$

substitute the values

$c^{2}=200^{2}+30^{2}-2(200)(30)cos(30\°)$

$c^{2}=30,507.695$

$c=174.66\ mi$

What is the simplified expression for,

Nostrana [21]

Here are a few rules you need to know for this equation:

Multiplying exponents of the same base: $x^m\times x^n=x^{m+n}$
Dividing exponents of the same base: $\frac{x^m}{x^n}=x^{m-n}$
Turning a negative exponent to a positive one: $x^{-m}=\frac{1}{x^m};\frac{1}{x^{-m}}=x^m$
