Answer:
Step-by-step explanation:
You only need one, but to use two let's go from cm to mm an then mm to inches. there are 100 mm^2 in a cm^2 so that's 100 mm^2/ 1 cm^2 and then there's 645.16 mm^2 in one square inch so that one will be 1 in^2/ 645.16 mm^2 so writing it out we get:
62 cm^2 * 100 mm^2/ 1 cm^2 * 1 in^2/ 645.16 mm^2
units all cancel out to get in^2 an then you just multiply 62*100/645.16 = 9.61 so that leaves us with 9.61 in^2.
Let me know if there's something you don't understand.

Answer:
40
Step-by-step explanation:
Subtracting a number k from 300 looks like this 300-k.
Adding a number k to 220 looks like this 220+k.
They are saying for some number k that we have 300-k and 220+k is the same value.
That is, 300-k=220+k.
This is the equation we are going to solve for your number.
300-k=220+k
Add k on both sides:
300=220+2k
Subtract 220 on both sides;
80=2k
Divide both sides by 2:
40=k
k=40.
So the number is 40.
Check: 300-40=260 while 220+40=260.
