Hi.

In an equilateral triangle, as the name implies, all the sides are equal in length.

You find perimeter by adding all the sides.

The formula for perimeter is 3<em>a </em>where <em>a</em> = the length of the side.

3(12) = 36 cm

The perimeter of the triangle is 36 cm.

AfilCa [17]

Given:

Total number of questions = 6

Choice for each question (in MCQ) = 4

Assuming that no questions are left unanswered.

To find:

The total number ways to answer the quiz, assuming that no questions are left unanswered.

Solution:

Here, Number of ways to answer each question = 4

To find the  total number ways to answer 6 MCQ, we have to have to multiply number of ways to answer each question 6 times.

Total number of ways to answer six-question quiz with 4-choice multiple choice questions is

4\times 4\times 4\times 4\times 4\times 4=4096

Therefore, the required number of ways is 4096.

ANSWER

D. A'(-5,0), B'(0,9) and (2,6)

The coordinates of triangle ABC are A(0,-5), B(-9,0) and C(-6,2).

A rotation of 90° clockwise about the origin has the mapping,

(x,y)\to (y,-x)

Therefore the image triangle has vertices

A'(-5,0), B'(0,9) and C'(2,6)

The correct choice is D.

X-5y=33<br> 5x-6y=70<br> solve the system by the addition method
BARSIC [14]

For this case we have the following system of equations:

x-5y = 33\\5x-6y = 70

We multiply the first equation by -5:

-5x + 25y = -165

Thus, we have the equivalent system:

-5x + 25y = -165\\5x-6y = 70

We add the equations:

-5x + 5x + 25y-6y = -165 + 70\\19y = -95\\y = - \frac {95} {19}\\y = -5

We find the value of the variable "x":

x-5 (-5) = 33\\x + 25 = 33\\x = 33-25\\x = 8

Thus, the solution of the system is:

(x, y) :( 8, -5)

Answer:

(x, y) :( 8, -5)
