Answer:

x = 8

Step-by-step explanation:

Since the triangle is isosceles then the 2 legs are congruent.

Given the perimeter is 66, then sum the 3 sides and equate to 66, that is

x + 4x - 3 + 4x - 3 = 66 , that is

9x - 6 = 66 ( add 6 to both sides )

9x = 72 ( divide both sides by 9 )

x = 8

Answer:

10 points

Step-by-step explanation:

Points scored in each of the first 3 quarter = x

Total points scored in the first 3 quarter = x + x + x

= 3x

Points scored in the fourth quarter = 14

Total points scored = 44 point

Total points scored = Total points scored in the first 3 quarter + Points scored in the fourth quarter

44 = 3x + 14

Subtract 14 from both sides

44 = 3x + 14

44 - 14 = 3x + 14 - 14

30 = 3x

Divide both sides by 3

x = 30/3

= 10

x = 10 points

Points scored in each of the first 3 quarter = x = 10 points

The school football team scored 10 points points in the first quarter

Answer:

-3x^2 - 21x

Step-by-step explanation:

This question is representing multiplying two functions :

We are finding f(x) * g(x)

We know that f(x) is -3x and g(x) is x + 7, therefore :

(-3x)(x + 7)

Follow FOIL :

First :

(-3x)(x)

-3x^2

Outer :

(-3x)(7)

-21x

Therefore the answer is :

-3x^2 - 21x

Answer:

x= 40

Step-by-step explanation:

The reason this is so is because a straight line's degree is always 180. And 4(40)-20=140 and 180-40=140. This is how you would work out the right side. This gives you your answer.

Answer:

40

Step-by-step explanation:

[tex]x + 4x - 20 = 180 \\ 5x = 180 + 20 \\ x = 200 \div 5 \\ x = 40[/tex]

Answer:

Kay sold 6 boxes and Ayan sold 19 boxes

Step-by-step explanation:

Let x be the number of boxes sold by Kay and

Let y be the number of boxes sold by Ayan

Then according to given statements, the equations will be:

[tex]x+y = 25\ \ \ Eqn\ 1\\x = y-13\ \ \ Eqn\ 2[/tex]

Putting x = y-13 in equation 1

[tex]y-13+y = 25\\2y-13=25\\2y=25+13\\2y = 38\\\frac{2y}{2} = \frac{38}{2}\\y = 19[/tex]

Putting y = 19 in equation 2

[tex]x = 19-13 = 6[/tex]

So we get x=6 and y=19

Hence,

Kay sold 6 boxes and Ayan sold 19 boxes

It is in tenths place.

Answer:

The values of x for which the model is 0 ≤ x ≤ 3

Step-by-step explanation:

The given function for the volume of the shipping box is given as follows;

V = 2·x³ - 19·x² + 39·x

The function will make sense when V ≥ 0, which is given as follows

When V = 0, x = 0

Which gives;

0 = 2·x³ - 19·x² + 39·x

0 = 2·x² - 19·x + 39

0 = x² - 9.5·x + 19.5

From an hint obtained by plotting the function, we have;

0 = (x - 3)·(x - 6.5)

We check for the local maximum as follows;

dV/dx = d(2·x³ - 19·x² + 39·x)/dx = 0

6·x² - 38·x + 39 = 0

x² - 19/3·x + 6.5 = 0

x = (19/3 ±√((19/3)² - 4 × 1 × 6.5))/2

∴ x = 1.288, or 5.045

At x = 1.288, we have;

V = 2·1.288³ - 19·1.288² + 39·1.288 ≈ 22.99

V ≈ 22.99 in.³

When x = 5.045, we have;

V = 2·5.045³ - 19·5.045² + 39·5.045≈ -30.023

Therefore;

V > 0 for 0 < x < 3 and V < 0 for 3 < x < 6.5

The values of x for which the model makes sense and V ≥ 0 is 0 ≤ x ≤ 3.

The values of x for which the model makes sense are 13/2 and 3

The equation that represents the volume of the box is given as:

[tex]V =2x\³ -19x\² +39x[/tex]

Factor out x from the above equation

[tex]V =x(2x^2 -19x +39)[/tex]

Expand the above equation, as follows

[tex]V =x(2x^2 -6x - 13x +39)[/tex]

Factorize the above equation

[tex]V =x(2x(x -3) - 13(x -3))[/tex]

Factor out x - 3

[tex]V =x(2x -13)(x -3)[/tex]

Equate to 0

[tex]x(2x -13)(x -3) = 0[/tex]

Solve for x

[tex]x = 0[/tex] or [tex]x = 13/2[/tex] or [tex]x = 3[/tex]

The value of x cannot be 0.

Hence, the values of x for which the model makes sense are 13/2 and 3

Answer:

332

Step-by-step explanation:

Since Dana had the closest guess with 325 people and Elijah had the second closest guess with 340 people we know that the actual number of guests is close to these values. Since Brady had the farthest guess then that means that the actual number of guests is higher than 325 and lower than 340. Therefore the actual number of guests can only be 332 as it is between Dana and Elijah's guesses but still favoring Dana, and also being farthest from Brady's guess.
