If the sides of a polygon are x + 3 units, 2x – 4 units, 5x units, and 7x + 8 units, then find the perimeter of the polygon.

3 0

Answer:

The answer is 15x + 7

Step-by-step explanation:

Since the perimeter of a REGULAR polygon is the number of sides multiplied by the length, and the lengths of the sides are all different, it can be assumed that this is an irregular polygon. That means the formula to find the perimeter changes to all the sides added together.

 1 x + 3

 2 x - 4

 5 x + 0

<u>+ 7 x + 8</u>

 15 x + 7

What is the equation of the line passing through the points (-25, 50) and (25, 50) in slope-intercept form?
babunello [35]

Answer:

Y = 50x

Step-by-step explanation:

Remember that slope intercept form is Y = mx + b indicating that m is the slope

To solve this equation use the formula

Y2 - y1 , x2 - x1:

50 - (- 50) = 100

25 - (-25) = 50

100/50 = 50/1

So the answer is y = 50x

(1, 7); slope = -1 please help fast
Harrizon [31]

Answer:

y = - x + 8

Step-by-step explanation:

Step 1:

y = mx + b     Slope Intercept Form

Step 2:

y = -x + b     Input Slope

Step 3:

7 = - 1 ( 1 ) + b    Input x and y

Step 4:

7 = - 1 + b      Multiply

Step 5:

b = 8     Add 1 on both sides

Answer:

y = - x + 8

Hope This Helps :)

A statue is mounted on top of a 16 foot hill. From the base of the hill to where you are standing is 77 feet and the statue subt
DanielleElmas [232]

Consider right triangle with vertices B - base of the hill, S - top of the statue and Y - you. In this triangle angle B is right and angle Y is 13.2°. If h is a height of the statue, then the legs YB and BS have lengths 77 ft and 16+h ft.

You have lengths of two legs and measure of one acute angle, then you can use tangent to find h:

\tan 13.2^{\circ}=\dfrac{\text{opposite leg}}{\text{adjacent leg}} =\dfrac{16+h}{77}, \\ \\ 0.2345=\dfrac{16+h}{77},\\  \\ 16+h=0.2345\cdot 77=18.0565,\\ h=18.0565-16=2.0565 ft.

Answer: the height of the statue is 2.0565 ft.
