Answer:
The value of
is -16.
Step-by-step explanation:
We need to evaluate
for x = -1, y = 5 and let us assume that z = 1
It can be simply done by putting the values of x,y and z in the given expression.

We know that the value of 4² = 16
So,

So, the value of
is -16.
The answer is d because the perimeter of 6 by 6 would be 24 and that is the smallest perimeter.
Draw the number line then put the numbers on the number line by twos. Fore example, 2-4-6-8-10
The highest common factor is 48.
