Answer:
144
Step-by-step explanation:
First, do the top and bottom. The top is 2*4*3 or 24, and the bottom is 6*4 or 24.
Now, do the sides. It is a staircase that you can split into 6 2x2 blocks, or 6*4=24. Do the same with the other side to get 24 again.
Now for the front and back. This is 2*4*3 and 6*4 again, or 24 and 24.
Now you have 6 24's so just multiply these and get 144.
There are the solutions for x+y=3 and they are
(0,3) (2,1) and (1,2)
and for -x+2y=6 is
(0,3) (2,4) and (1 7/4)
hope this helps
Answer:
f(x) = f(-x) = x^2 -1 is an <u>even</u> function
Step-by-step explanation:
When f(x) = f(-x), the function is symmetrical about the y-axis. That is the definition of an <em>even</em> function.
___
An odd function is symmetrical about the origin: f(x) = -f(-x).
