Answer:
B) It is irrational and equal to 
Step-by-step explanation:
The expression, 
, is an irrational expression because it contains two irrational numbers, 
and 
. Both number are not perfect square. there is no whole number that would be squared that will give you 18 nor 2.
The expression can be equals the following:
The answer is 8n2 + 26n + 6
A unit rate can be represented as"The number of x's per 1." They are often given in scenarios of several days, and you need to calculate what happened in 1 day.
For example:
John sells 60 watermelons in 30 day. What is the unit rate of his sells?
If he sells 60 in 30 days, that means he sells 2 watermelons per day. Therefore, the unit rate is 2.
The equation that you would use would be 4^2-2^2=a^2 (a^2+b^2=c^2). you would have to square the numbers and subtract. then your answer should be the square root of 12. So the answer technically would be C, but it worded kinda weird. It should say "the square root of 12". Hope this helped.
