Answer:
The ones that give a rational number answer are:
C+D
A*B
C*D
A*A
Step-by-step explanation:
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
Answer:
y = 4x - 48
Step-by-step explanation:
y = 1/4 x - 12
x = 1/4 y - 12
4x = y - 48
y = 4x - 48
C = 0.3*-2.7 = -0.81

Answer:
x = 2.5
Step-by-step explanation:
8x - 10 = 4x
=> 8x - 4x = 10
=> 4x = 10
=> x = 10 / 4
=> x = 2.5
