A regular hexagon is shown.
-BARSIC- [3]

Answer:

(C)9 in.

Step-by-step explanation:

The apothem of a regular polygon is a line segment from the center to the midpoint of one of its sides.

Given the hexagon with a radius of 10 inches

The apothem AB divides the side of the hexagon into two equal parts of 5 Inches as seen in the attached diagram.

Using Pythagoras Theorem

10^2=5^2+|AB|^2\\|AB|^2=10^2-5^2\\|AB|^2=75\\|AB|=\sqrt{75}\\ |AB|=8.66$ in\\\approx$ 9 in (rounded to the nearest inch)

What's the answer for (2+i)(i+2i)?​
slava [35]

Answer:

\boxed{ \bold{ \huge{ \boxed{ \sf{3 {i}^{2}  + 6i}}}}}

Step-by-step explanation:

\sf{(2 + i)(i + 2i)}

Use the distribute property to multiply each term of the first binomial by each term of the second binomial.

⇒\sf{2(i + 2i) + i(i + 2i)}

⇒\sf{2i + 4i +  {i}^{2}  + 2 {i}^{2} }

Collect like terms

⇒\sf{3 {i}^{2}  + 6i}

Hope I helped!

Best regards!

You need to find the GCF of 256 and 400 Would you rather list their factors or use the prime factorization
trasher [3.6K]

If you were looking for the greatest common factor, you'd want to see the list of their factors.

A prime factorization breaks it down as far as possible and as a result has as few high numbers as possible. If you want the number to be as great as possible, you would want to see the list of all the factors.
