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:

Take LHS
49 - 4
We can write 49 as
and 4 as
.
then;

Now, use the difference of square identity;
here a =7 and b = 2

or
= RHS proved!
therefore, the difference of square polynomial identity should be used to prove that 49-4 =45
Answer:
5
Step-by-step explanation:
26 × 10 ÷ 100 = 52 · x ÷ 100
260 = 52 · x
x = 5
Answer:
Least common multiple (LCM) of 12 and 24 is 24.
Step-by-step explanation:
Answer: $6.39
Step-by-step explanation: 31.95 divided by 5
Well the opposite of a positive number is a negative, so if I am correct,
-30 / -6 would be 5, and 5 + -8 would be -3.
So -3 would be your answer.
