5 0

Answer:

{12,15}

Step-by-step explanation:

54 = 2(L + W)

27 = L + W

27 - L = W

LW = 180

L(27 - L) = 180

27L - L2 = 180

0 = L2 - 27L + 180                FOIL

0 = (L - 12)(L - 15)

{12, 15}

Tia went home and said to her mom,"I learned that 10 to the power of 4 is the same as 40,000."

Tia made a mistake in her thinking. Exponent represents the number of zeros.

10^4 means we multiply 10 four times

10^4= 10*10*10*10=10000

For exponent 4, we put 4 zeros. So answer is 10,000.
