Answer:
20.52
Step-by-step explanation:
I used a calculator
Answer: 52 cm
Step-by-step explanation:
P = 10 + 16 + 10 + 16 = 52 cm
-7x - 2y = 19
4x + y = -12
Set y equal to each other (opposite signs are fine and you could also set x equal instead of y)
-7x - 2y = 19
8x + 2y = -76
Add equations together
x = -52
Plug x value into an equation
4(-52) + y = -12
Solve for y
-208 + y = -12
y = 196
Hope this helps! ;)
