If you would like to find the discriminant of the quadratic equation 0 = 2x^2 + 3x - 5, you can do this using the following steps:
<span>0 = 2x^2 + 3x - 5
0 = ax^2 + bx + c
a = 2, b = 3, c = - 5
</span>D = b^2 - 4 * a * c = 3^2 - 4 * 2 * (-5) = 9 + 40 = 49
The correct result would be 49.
Answer:
A
Step-by-step explanation:
4 x $0.85= $3.40
$9-$3.40= $5.60
Answer:
See below
Step-by-step explanation:
1. 12
2. 15 [3*12-21 = 15]
3. 24 [3*15-21 = 24]
4. 51 [3*24 - 21 = 51]
2/4 = 0.5
3/4 = 0.75
7/8 = 0.875
3/8 = 0.375
So the answer for number 3 is p because p is the only one right on top of 4
But I dont know the answer for number 4 but I think its 2 I might be way off but its my guess.
Hope number 3 helps
