Answer:
k= 1/5
Step-by-step explanation:
x is proportional to y
x = ky (k is const.)
k = x/y
k= 5/25
k = 1/5
Answer:
2xy
Step-by-step explanation:
Here, we want to obtain the number with the smallest square
To get this, we simply find the nearest number square which is 2
The nearest x squared which is x (to get x^4)
The nearest y squared which is y (to get y^2)
Thus, the smallest number so we get a square will be; 2xy
Okay so basically it's like 4 to the power of 5 and like that and the • means multiply
