Answer:

3.75*A + 2.50*D = 35

A + D = 12

A = 12 - D

3.75*(12-D) +2.5*D= 35

45 - 3.75D + 2.5D = 35

45 - 1.25D = 35 |-35

10 - 1.25D = 0 |+1.25D

10 = 1.25D | /1.25

8 = D

A+D=12

A+8=12 |-8

A=4

In order to calculate the new vertices, we simply add 1 to the value of x in each point since the translation is towards the positive x-axis and subtract 3 from the y values of each point since the translation is towards the negative y-axis.
