Answer:
14
Step-by-step explanation:
you can simplify it by turning a²+b²/a-b
into
(a-b)²+2ab / a-b
eliminate the fraction
a-b +2ab
a=-1
b=-5
-1-(-5)+2*-1*-5
-1+5+10 = 14
6*2=12
32-12=20
20/2=10.
Perimeter is all the way around an object. So take 6 two times and minus that from 32. Answer of that divide by 2 to get the length. Length of one side is 10 ft.
Answer:
It's choice B.
Step-by-step explanation:
When r= -11,
x^2 + 8x - 33 = (-11)^2 - 88 - 33
= 121 - 88 - 33
= 0
- so x = -11 gives a zero value and is a solution to the equation.
Answer:
D
Step-by-step explanation:
There is no data set so there is no data to find the mean of.
Yes because the median and range are not a function of the totality of the sample set, the median is just value that is halfway of the set and the range is the difference of the highest and lowest value. As long as the lowest and highest value and the halfway value are the same in each set, the median and range will be equal no matter what the other values of the set are.
