it's easier b or d I'm not sure
The equation in the form 0 = ax^2 + bx + c is:
0 = x^2 + x + 2
The discriminant = b^2 - 4ac
Discriminant = (1)^2 - 4(1)(2)
= 1 - 8
= -7
Answer:

Step-by-step explanation:
subsitude the values into the formula i gave you. you should be able to get the answer.
Answer:
23/60
Step-by-step explanation:
All fractions of tiles, when summed up, need to be 1
Indian red is 1/4 of the tiles
Tuscan blue is 1/6 of the tiles
Fucalyptus is 1/5 of the tiles
Sand is X of the tiles (X is the fraction we want to know)
So, we can formulate the equation:
1/4 + 1/6 + 1/5 + X = 1
applying LCM, we have:
(15 + 10 + 12 + 60X) = 60
60X = 23
X = 23/60
