Answer:
Option A is correct
Difference of squares identity should be used to prove 49-4 =45
Step-by-step explanation:
Prove that : 49 - 4 = 45
Polynomial identities are just equations that are true, but identities are particularly useful for showing the relationship between two apparently unrelated expressions.
Difference of the squares identity:
80% bc 48 divided by 60 is 0.8 so answer is 80%
The decrease was 3. (from 30 down to 27)
Always calculate the decrease as a percent of the ORIGINAL number.
3/30 = 0.1
To change a decimal to a percent, move the point 2 places that way ==> .
0.1 = 10% .
When you go from 30 to 27, that's a decrease of 10% .
