Answer:
B
Step-by-step explanation:
5a^2 - 44 = 81 Add 44 to both sides
5a^2 = 81 + 44 Collect like terms
5a^2 = 125 Divide both sides by 5
a^2 = 125/5
a^2 = 25 Take the square root of both sides
√a^2 = √25
a = +5
a = -5
The answer is B

Answer:
C)265
Step-by-step explanation:
To find the median you list all the numbers in order from least to greatest. The number in the middle is the median.
In this case there are two middle number so you have to add them together then devide them by 2.
700, 740, <u>810, 900</u>, 1050, 1120.
810 + 900 = 1,710
1,710/2 = 855.
Your median is 855.
To find the difference you just subtract the two numbers.
1,120-855= 265.
