Answer:

the oldest is 31 years old, the youngest is 15.5 years old, and the middle is 10.5 years old

Step-by-step explanation:

First you take the two halves from 10.5 and 15.5 and add the two halves to get 1. So you would make an equation. The one I used was (10+1)=(15+31)= 57

Write the slope-intercept form of the equation of the line through the given points.
MatroZZZ [7]

Answer:

y = x-4

Step-by-step explanation:

First find the slope

m = ( y2-y1)/(x2-x1)

   = ( -3 -1)/( 1 - 5)

   = -4/-4

   = 1

Then using slope intercept form

y = mx+b where m is the slope and b is the y intercept

y = 1x+b

Substitute one of the points in

1 = 5 +b

1-5 = b

-4 =b

y = x-4

The polynomial x^2-18x+81 represents the area(in square feet) of a square courtyard. Write an expression for the perimeter of th
vovangra [49]

Answer:

4x - 36 feet

Step-by-step explanation:

The area A of a  square whose sides are s units is given as

A = s * s

Given that the area A = x^2-18x+81, factorizing

A = x^2-9x-9x+81

A= x(x-9)-9(x-9)

A = (x-9)(x-9)

A = (x-9)^2

This means that the size of each side of the square  courtyard is x-9 feet long

Recall that the perimeter P of a square whose side is s long is given as

P = 4s hence since the side of the courtyard is x - 9 feet, the perimeter of the courtyard

P = 4(x-9)

= 4x - 36 feet
