a rectangle has a height of n3+4n2+3n and a width of n^3+5n^2 express the area of the entire rectangle
alukav5142 [94]

<u>Given</u>:

It is given that the height of the rectangle is n^3+4n^2+3n

The width of the rectangle is n^3+5n^2

We need to determine the area of the entire rectangle.

<u>Area of the rectangle:</u>

The area of the rectangle can be determined using the formula,

A=height \times width

Substituting the values, we have;

A=(n^3+4n^2+3n)(n^3+5n^2)

Multiplying each term within the parenthesis, we get;

A=n^{3} n^{3}+n^{3} \cdot 5 n^{2}+4 n^{2} n^{3}+4 n^{2} \cdot 5 n^{2}+3 n n^{3}+3 n \cdot 5 n^{2}

Simplifying, we get;

A=n^{6}+5 n^{5}+4n^{5}+20 n^{4}+3  n^{4}+15 n^{3}

Adding the like terms, we have;

A=n^{6}+9n^{5}+23 n^{4}+15 n^{3}

Thus, the area of the entire rectangle is n^{6}+9 n^{5}+23 n^{4}+15 n^{3}

I need the answer. Please help.
gavmur [86]

Answer:

300°

Step-by-step explanation:

To convert from radians to degrees

degree = radian × \frac{180}{\pi } , then

degree = \frac{5\pi }{3} × \frac{180}{\pi } ( cancel π on numerator/ denominator )

            = \frac{5(180)}{3}

            = 5 × 60°

            = 300°
