Answer: ( 6, -4)

Step-by-step explanation:

Substitute the value of y in the second equation into the first equation and solve for x.

5x - 7(-x + 2) = 58 Distribute

5x + 7x - 14 =58 Combine like terms

12x - 14 = 58

+14 +14

12x = 72

x = 6

Input the value for x intro one of the equations to solve for y .

5(6) - 7y = 58

30 -7y = 58

-30 -30

-7y = 28

y = -4

Tamiku [17]

Answer: 16 units

Step-by-step explanation:

Point A and Point B are 5 units apart on the x-axis.

Since this is a rectangle, the opposite side is equivalent.

Point A and Point C are 3 units apart on the y-axis.

Same thing applies for these points.

5+5+3+3=16 units
