Answer:
76
Step-by-step explanation:
4^2 x 5^2 - 18^2
PEMDAS is our acronym for order of operations: Parentheses, exponents, multiplication, division, addition, subtraction.
Since we have no parentheses, we'll calculate the numbers and exponents (PEMDAS) first. "to the power of 2" is also called "squared" and means multiplying that number by itself.
(4x4) x (5x5) - (18x 18)
=16 x 25 - 324
Now we multiply: (PEMDAS)
= 400 - 324
then subtract: (PEMDAS)
=76

<span>Christopher bought a new watch at the store when they were having a 20% off sale.
</span><span>If the regular price of the watch was $48, what did Chris have to pay after the discount was applied?

Answer:
the correct answer is C: 38÷16
38÷16 = 2.375
Area = length x width
Perimeter = 2(l + w)
Let's imagine one of the sides is 6. The other side would have to be two, and the perimeter would be 16.
If one of the sides is 4, the perimeter would be 14.
If one of the sides is 1, the perimeter would be 26.
