Answer:

Step-by-step explanation:

10 / 2 * ( 9 + 3 )

remember the order of operations: parenthesis first

10 / 2 * ( 9 + 3 )

10 / 2 * 12

now there is only multiplication and division, so it shouldn't matter which is done first, the answer will still be the same

10 / 2 * 12

5 * 12

Find the area of an equilateral triangle (regular 3-gon) with the given measurement. 6-inch radius A = sq. in.

katovenus [111]

$\bf \textit{area of an equilateral triangle}\\\\
A=\cfrac{s^2\sqrt{3}}{4}\qquad 
\begin{cases}
s=length~of\\
\qquad a~side\\
-------\\
s=6
\end{cases}\implies A=\cfrac{6^2\sqrt{3}}{4}\implies A=\cfrac{36\sqrt{3}}{4}
\\\\\\
A=9\sqrt{3}$

D₁ vide using x² - 2x² 2× +3× -5 by ×-3 using synthetic division. <br>

Vaselesa [24]

Answer:

Step-by-step explanation:

I think you are trying to use synthetic division for

$x^{4} -2x^{3} -2x^{2} +3x-5$ divided by x-3

First

x -3 = 0 , make it equal to 0 and add 3 to both sides

x = 3

Then we write all the coefficients and continue with

a pattern of multiply by 3 and add to the next coefficient.

Assume that two figures on a flat surface, A and B, are similar.

lawyer [7]

A. ratio of areas = 2^2 /5^2 = 4/25

B 14^2 : 1 = 196:1

C. ratio of perimeters would be sqrt81 = 9 times
