Rewrite it in the form a^2 - b^2, where a = x and b = 5
x^2 - 5^2
Use the Difference of Squares: a^2 - b^2 = (a + b)(a - b)
<u>= (x + 5)(x - 5)</u>
Answer:
3 3/16 lbs is the total amount the puppies weigh
Answer:
Step-by-step explanation:
First you need to find the mean of the set so 10+12+8+2=32/4=8
Mean=8
Then subtract the mean of each number and square the result
10-8=2^2=4
12-8=4^2=16
8-8=0^2=0
2-8=-6^2=36
new data set: 0,4,16,36
Next find the mean of this set of data
0+4+16+36=56/4=14 now take the square root of that mean
sqrt14=3.74
Hope this helps
