Step-by-step explanation:
-8x - 4y = -20...divide by -4
2x - y = 5...rearrange
2x - 5 = y
this is the same as the other equation...this means they are the same line with infinite solutions
The answer is inconsistent
If all the side on the square are 2.5 cm then you would multiply 2.5 times 4 (we get the four from the number of sides on the shape) and your answer is 10 cm
