Answer:
Option (1)
Step-by-step explanation:
Coordinates of the vertices are A(-2, 1), B(2, 7), C(8, 3) and D(4, -3)
Since ABCD is a square,
Perimeter of a square = 4 × (length of a side)
= 4 × (AB)
Formula to calculate the distance between two points 
and 
is,
d = 
Therefore, distance between two points A(-2, 1) and B(2, 7) will be,
AB = 
AB = 
AB = 
AB = 
Now area of square ABCD = 4 ×
= 
unit
Therefore, option (1) will be the answer.
The arrangement should be based on the decreasing degree of the terms which may be determined by the variable x as it should come first in alphabetical order. The polynomial is then,
10x³ + 2x²y + 2xy^4 - 3y²
The degree is equal to the sum of the exponents. Thus, the answer is 5 and it is letter D.
Hi There!
-----------------------------------------
We Know:
$35 per person.
Guides Fee: 10 * 35 = 350
425 - 350 = $75 (guide fee)
-----------------------------------------
Part A:
The problem states to put c as cost and p as number of people:
c = 35p + 75
b = $75 (guide fee)
If you don't need the one above, this is just in slope intercept form.
y = 35x + 75
b = $75 (guide fee)
Answer: c = 35p + 75 or y = 35x + 75
-----------------------------------------
Part B:
How much would it cost for 15 people?
Lets use: c = 35p + b
Substitute p for 15 people and b as $75 for the guide fee: c = 35(15) + 75
Simplify: c = $600
Answer: The total cost for 15 people is $600.
