Answer:
x=3,y=1
Step-by-step explanation:
2^x+y=16,3^x-y=9
16=2^4,9=3^2
x+y=4,x-y=2 add both
2x=6,x=3
3-y=2,y=1
Answer:
3 boxes
Step-by-step explanation:
you would divide 12 by 4 and get 3 so shade in 3 boxes
let the short side = x
Long side = 3x
Middle side = 3x -3
x + 3x + 3x -3 = 32
Simplify:
7x -3 = 32
Add 3 to both sides:
7x = 25
Divide both sides by 7:
X = 5
answer: shortest side = 5cm
