The answer is B as the coefficient represents the number of legs
Answer: (D) 2.394 * 10^-1
Step-by-step explanation:
(4.2 * 10^-1) (5.7 * 10^-1)
= 2.394 * 10^-1
48: 1, 2, 3, 4, 6, 8, 12, 16, 24, 48
64: 1, 2, 4, 8, 16, 32, 64
gcf: 16 in each row
Answer:

» Collect like terms, r terms on the left hand side by subtracting r from both sides and adding st to both sides

» On the left hand side, factorise out r

That "equation" has an infinite number of "solutions", because
no matter what 'r' is, it's always a true statement.
The statement is equivalent to saying "I am I." or "You are you."
