Answer:
Assuming you want to find u, u = 9.29
Step-by-step explanation:
u - 5.3 = 3.99
Add 5.3 to both sides.
u = 3.99 + 5.3
u = 9.29
<u><em>Answer:</em></u>
D. 60
<u><em>Explanation:</em></u>
<u>The general form of the quadratic equation is:</u>
ax² + bx + c = 0
<u>The given equation is:</u>
3x² + 6x = 2
This can be rewritten as:
3x² + 6x - 2 = 0
<u>By comparison, we can find that:</u>
a = 3
b = 6
c = -2
<u>Now, the discriminant of a quadratic equation is given by:</u>
b² - 4ac
<u>Substitute with the given values to get the discriminant for the given equation as follows:</u>
b² - 4ac = (6)² - 4(3)(-2)
= 36 - (-24)
= 36 + 24
= 60
Hope this helps :)
