20.6

Step-by-step explanation:

Coordinates given:

D(-3,2)
E(4,2)
F(4,-3)

Plotted, these points give a right triangle with hypotenuse DF

Distance DE = 4 - (-3) = 7
Distance EF = 2 - (-3) = 5
Distance DF = √(7²+5²) = √84 = 8.6

Perimeter

P = 7 + 5 + 8.6 = 20.6

1) The sum of three numbers is 22. The second is 3 more than the first. The third is

Mila [183]

Answer: The numbers are 5, 8, and 9

Step-by-step explanation:

x+y+z=22

y=x+3

z=2x-1

After you have those three equations, you can plug the y and z value into the first equation.

You get x+x+3+2x-1=22, so 4x+2=22

Therefore, 4x=20, so x=5

If x=8, then y=5+3, so y=8

Also, z=2(5)-1, so z=9
