Answer:
-1/240 (Might be wrong though)
Step-by-step explanation:
The first thing we need to do is multiply 1/15 and 1/16 because product means the answer to a multiplication equation.
1/15 times 1/16 = (1*1)/(15*16) = 1/240
Now that we know the product 1/240, we just have to find the opposite, which is -1/240 because you just add a negative sign in opposites( even in negative numbers)
Try using negative numbers

Answer:
C) 32 * 2**1/2
Step-by-step explanation:
For rectangle P = L + W = 24 but L = 2W so
2W + W = 24
3W = 24
W = 8 and L = 2W = 16
A = L * W = 16 * 8 = 128
SO for the square with the same area
A = L * L = 128
L**2 = 128
L = 8 * 2**1/2
P = 4L = 32 * 2**1/2
What you want to do is find the comon demominator and than go from rhere pluse you should be able to go and look back at the lesson if you dont get ut well its like that for me
