# Ineed on this! which of the following is an irrational number? a. √1 b. √9 c. √45 d. √81 coreyrineer2791

i just took the test, the correct answer is .. 31.5 in. harleycrider2251

step-by-step explanation:

divide the length of a'c' by the length of ac to get a scale factor of two

& then reflect vertically (over the y-axis)

so your answer is dilation by a scale factor of 2 followed by reflection over the y-axis andy6128

C sqrt(45) is irrational

Sqrt(1)=1 rational

Sqrt(9)=3 rational

Sqrt(81)=9 rational

Sqrt(45)=9*sqrt(5) irrational

So C sqrt(45) is the answer

Hope this helped. Have a great day!  ### Other questions on the subject: Mathematics Mathematics, 21.06.2019, genyjoannerubiera Mathematics, 21.06.2019, hrcatena Mathematics, 21.06.2019, maggie3541
