Astudent factors a6 - 64 to (a2 - 4)(a4 4a2 16).
which statement about (a2 − 4)(a4 4a2 16) is correct?
the expression is equivalent and is completely factored.
the expression is equivalent, but the (a2 – 4) term is not completely factored.
the expression is equivalent, but the (a4 4a2 16) term is not completely factored.
the expression is not equivalent.

Option (b) is correct.

The expression is equivalent, but the  term is not completely factored.

Step-by-step explanation:

Given :  a student factors to

We have to choose the correct statement  about   from the given options.

Given   is factored to

Consider    

Using algebraic identity,

comparing and b = 4, we have,

Thus, the factorization is equivalent but we can simplify it further also, as

Using algebraic identity,

Thus,

Can be written as

Thus, the expression is equivalent, but the  term is not completely factored.

Option (b) is correct.

b

Step-by-step explanation:

b on edg lol i just want points

see below

step-by-step explanation:

7.   there are 10 data points in the set.   the middle point is between 5 and 6.   the middle point in the top half is 8   and the middle point in the bottom half is 3. to find the iqr , take point 8 and subtract point 3

mid term   point 8 = 100   point 3 = 88

iqr = 100-88 = 12

final   point 8 = 93   point 3 = 78

iqr = 93 - 78 = 15

the final has the greatest iqr

6.   b - there is a high data value that causes the data set to be asymmetrical for the males: the data for males are high and asymmetrical .   there is an outlier for the males that skews the data

5.   the   iqr is a better measure of spread for the movies and basketball games.   since the basketball game has an outlier, we do not want to use standard deviation for measurement.  

3.   the exam median is much higher than the class median.   the median line is farther to the right on the exams

2.   there is no way to tell what the means are from the box and whisker plots.
