Given the two expressions shown below: a: square root of 4 plus square root of 25 b: square root of 4 plus square root of 2 which statement best describes the two expressions? a. both are rational. b. both are irrational. c. a is rational, but b is irrational. d. a is irrational, but b is rational.

A is rational.

The square foot of 4 is 2, and the square root of 25 is 5.
When they are added, you get 7.
7 can be expressed as a fraction, 7/1, so it is rational.

B is irrational.

The square root of 4 is 2, like I said above.
The square root of 2 is an irrational number.
When you add an irrational number, the sum is irrational too.
So, B is irrational.

Therefore, the answer is C.

Hope this helps!

The major difference is that a histogram is only used to plot the frequency of score occurrences in a continuous data set that has been divided into classes, called bins.  bar charts, on the other hand, can be used for a great deal of other types ofvariables  including  ordinal  andnominal  data sets.
