Discriminant = square root (b^2 -4*a*c)
square root (64 -4*1*12) =
square root (16) =
4
Therefore it has 2 rational soltions
Answer:
384 cm
Step-by-step explanation:
7.5 x 24 = 180
8.5 + 7.5 = 16
16 x 24 = 384
156°
D is a 24° angle, and is placed in a 90° angle, so 90-24=66
C is a right angle, so 90+66=156°
Hope this helped!
I'm going to answer this as a process going down:
√x+1=6 The statement
x+1=6² Move the sqrt to the other side
x=6²-1 As well as the +1
x=36-1 Simplified the equation
x=35 Final answer
