Answer:

perimeter = 52

Step-by-step explanation:

side of square = 2x + 1

  • so first lets find the perimeter of square

p = 4 × s (side)

p = 4(2x +1)............. from the given

p = 8x + 4...... we will come back for this equation

side of trianles = 2x,2x,3x + 10

  • second lets find the perimeter of triangle

p = s + s + s ( all the three sides)

p = 2x + 2x + 3x + 10

p = 7x + 10........we got another equation we will use it later

  • The question says the perimeter of square and the perimeter of triangle are equal so
  • 8x + 4(the perimeter of square we solved before) = 7x + 10(the perimeter of triangle we solved before)

8x + 4 = 7x + 10

8x - 7x = 10 - 4

x = 6 ... now lets substitute x

8x + 4

8 × 6 +4

48 + 4

52

the same thing will happen if we substitute for the perimeter of triangle too.

hope u like it ‍❤️‍❤️‍‍❤️‍

Find the constant of variation (k) where y varies directly with x. y = 2, when<br> X = 6.
ExtremeBDS [4]

Answer:

The graph below models the value of a $20,000 car t years after it was purchased.

                    Value of Car

A graph titled Value of Car has years on the x-axis and Dollars on the y-axis. A line curves down and goes through points (0, 20,000), (4, 10,000), and (14, 2,000).

Which statement best describes why the value of the car is a function of the number of years since it was purchased?

Each car value, y, is associated with exactly one time, t.

Each time, t, is associated with exactly one car value, y.

The rate at which the car decreases in value is not constant.

There is no time, t, at which the value of the car is 0.

Solve the proportions
DanielleElmas [232]

Do cross multiply or butterfly.   For example first one. 18/x=6/10  So cross multiply  18×10 =6x 180=6x Divide both sides by 6 to get x alone 180÷6=30 So x =30  Do the same to rest
