In standard form the answer is
Answer:
A. (x+12)(x-12)
Step-by-step explanation:
Use foil method
x * x = x^2
x * - 12 = - 12x
12 * x = 12 x
12 * - 12 = - 144
x^2 [- 12x + 12x= 0x = 0] - 144
x^2 + 0 - 144 =
x^2 - 144 #
Answer:
1. Put the numbers in order.
2. Cross off high/low pairs.
3. Add the leftover numbers.
4. Divide the sum by 2.
Step-by-step explanation:
Given:
24, 16, 23, 30, 18, 29
The ordered steps involved in Calculating the median of the data set given :
1.) put the numbers in order: This involves arranging the numbers in the dataset usually in ascending order :
16, 18,23,24,29,30
2.) Cross off high/low pairs: take out equal amount of input from both the left and right hand side. Here we have (23, 34) left
3) Add the leftover numbers: Since the values left is more than one, both values are summed, we have (23+24) = 47
4.) Divide the sum by 2 : Get the average of the two numbers to obtain the median value. Here the average is (23+24)/2 = 47/2 = 23.5
