Answer:
Step-by-step explanation:
A looks good
For this case as MNOP is a square then the angles of each vertex are equal to 90 degrees.
Therefore, we have the following equations:

From these equations, we can clear the values of the unknowns.
For equation 1 we have:


For equation 2 we have:


Answer:
The values of t and f are given by:

Answer:
25 pounds
Step-by-step explanation:
Let us assume that initially, 1 pound of whole chicken costs x.
So, initially 20 pounds of whole chicken costs 20x.
Now, the price is reduced by 20%.
That means that 1 pound of whole chicken now costs
Therefore, with a 0.8x amount of money, we can now purchase 1 pound of the whole chicken.
Hence, with a 20x amount of money, we can now purchase
pounds of the whole chicken.
The correct answer is 427
8-2=6
180×6=1080 degrees
sum of interior angle of an octagonal box = 1080 degrees
