I'm pretty sure the answer is exponent since it tells you how many times to multiply the number beside it by itself.
Example:

It is NOT 3 × 4 = 12
It is 3 × 3 × 3 × 3 = 9 × 3 × 3 = 9 × 9 = 81

Answer:
The correct option is B.
Step-by-step explanation:
The given vertices are (-4,2),(1,2),(1,-3) and (-4,-3).
Plot these point on a coordinate plate. From the graph it is noticed that the given quadrilateral is a square.
Distance formula:

Use distance formula to find the side length.


Since both consecutive sides are equal therefore it is a square.
Area of a square is

Where, a is side length.
The side length of the square is 5. So, area of ABCD is


Therefore the area of quadrilateral is 25 units square. Option B is correct.
Answer: this is the answer
( {x}^{3} ) {}^{ - 5} = {x}^{ - 15}
Step-by-step explanation:
(5x+2)(8x^2+1) is the answer when factored.
Answer: 504
Step-by-step explanation:
When we select r things from n things in a order , we use permutations.
Formula for permutation: 
Given : The number of family members who are potential kidney donors. = 9
Number of people needed to be selected for best match, a second-best match, and a third-best match ( in an order)=3
Then, the number of possible orders are = 

Hence, the number of possible orders 504.
