The ones that give a rational number answer are:
C+D
A*B
C*D
A*A
A+B does not give a rational number answer; √3+2√3 = 3√3
C+D is a rational number; √25=5 and √16=4; 5+4=9.
A+D is not a rational number; √3+√16 = √3+4
A*B is a rational number; √3*2√3 = 2√9 = 2*3 = 6
B*D is not a rational number; 2√3*√16 = 2√3*4 = 8√3
C*D is a rational number; √25*√16 = 5*4 = 20
A*A is a rational number; √3*√3 = √9 = 3
The answer is A. Just remember the acronym for foil.
Answer:
First, finish the brackets, multiply what’s in the bracket by the outer side of the bracket
-24+12d=2d-6+22
Then, collect like terms
12d-2d=-6+22+24
10d=16+24
10d=40
d=40/10
d=4
