Answer:
13
Step-by-step explanation:
15 - 4 + 7 - 5 = 13
Simply expand the brackets and subtract and add accordingly.
let the length of each shorter side be x
length of longer side= x+14
2(x+14) + 2x = 48
2x + 28 + 2x = 48
4x + 28 = 48
4x = 48-28
4x = 20
x = 5
shorter side = 5cm
(x-3)=-3x+25
Because we know that y=x-3 so we put that in place of y in the equation
