Answer:

Step-by-step explanation:

5x – 4y = -10

y = 2 x – 5

Rearrage the equation:

5x – 4y = -10 (1)

-2 x +y = 5. (2)

pluging variable y equation2 in 1

5x - 4•(2x-5) = -10

-3x = -30

Solve equation [1] for the variable x

3x = 30

x = 10

y = 2x-5

Use the x value to solve for y

y = 2(10)-5 = 15

x= 10

y= 15

For AD:
AD=root((c-0)^2 + (d-0)^2)=root((c)^2 + (d)^2)
For BC:
BC=root(((b+c) - b)^2+(d-0)^2)=root((c)^2+(d)^2)
For AB:
AB=root((b-0)^2 + (0-0)^2)=root((b)^2 + (0)^2)=root((b)^2)
For CD:
CD=root((c-(b+c))^2 + (d-d)^2)
CD=root((b)^2 + (0)^2)
CD=root((b)^2)
