Answer:

14cm

Step-by-step explanation:

Given parameters:

        perimeter of the triangle  = 42cm

        length of side = (3s + 2)cm

Unknown:

Find the length of each side = ?

Solution:

The perimeter of a body is the sum of all its sides.

 In this problem, we have been given an equilateral triangle. For such a triangle, all the sides are equal. So the perimeter is the sum of all the three sides;

     (3s + 2) + (3s + 2) + (3s + 2)  = 42

            9s + 6 = 42

            9s  = 42 - 6

            9s = 36

              s  = 4;

The length of its sides = 3s + 2

                                     = 3(4) + 2

                                     = 12 + 2

                                     = 14cm

Answer:

{-4≤ x≤ 4}

The average rate of change would be 1 for f(x) = x.

Step-by-step explanation:

Suppose we have a range a≤x≤b, then the average rate of change can be calculated by =f(b) - f(a)/b-a

The given range lies from -4 to 4 as {-4≤ x≤ 4}

The range of this is from -4 to 4.It includes all the numbers ranging from -4 to 4.

The average rate of change of the function is calculated by

= f(4) - f(-4)/4-(-4)

Suppose f(x)= x  then f(4)= 4   and f(-4)= -4

Then

4- (-4)/ 4- (-4)

= 8/8= 1

So the average rate of change would be 1.

Step 5 is wrong, because you multiply or divide before you add or subtract.

Answer:

-5x+(- 15 ) = 20

x=-7

Step by Step

-5x+(-15)= 20 becomes

-5-15=20 add 15 tp (15 and 20)

-5x=35 ( divide by 51

Answer:

perfect positive association.

Step-by-step explanation:

A perfect positive association means that a relationship appears to exist between two variables, and that relationship is positive 100% of the time. In statistics, a perfect positive association is represented by the value +1.00, while a 0.00 indicates no association

Answer:

n=8

Step-by-step explanation:

-6=n/2-10 -- switch sides

n/2-10= -6 -- add 10 to both sides

n/2-10+10= -6+10 -- simplify

n/2=4 -- multiply both sides by 2

2n/2=4 times 2 -- simplify

n=8 -- answer

Answer:

x=1/3. y=3/2

Step-by-step explanation:

x+y=2. =>equation 1

2x-y = 1. => equation 2

equation 1 + equation 2,

x+y+(2x-y) = 2-1

x+y+2x-y = 1

3x = 1

x=1/3

plug in value of x in equation 1,

1/2 + y = 2

y= 2 - 1/2

y = 3/2

The equation which has no solutions is 5 x + 5 y = 10 and 2 x + 2 y = 4

An equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

As,

5 x + 5 y = 10 and 2 x + 2 y = 4

a1= 5, b1= 5, c1 = -10

a2= 2, b2= 2, c2 = -4

Now, a1/ a2 = 5/2

b1/ b2= 5/2

c1/ c2= -10/-4 = 5/2

Hence, a1/a2= b1/b2= c1/c2

So, the pair of equation has no solution.

Answer:

Tickets to workers= 32

Step-by-step explanation:

Giving the following information:

Total tickets= 192

They gave away 5 times as many tickets to listeners as they gave to employees.

We will use the rule of 3:

6/6=192

5/6= ? = 192*(5/6) = 160

They gave 160 tickets to listeners.

Tickets to workers= 192 - 160= 32

Prove:

32*5= 160
