Answer:
<h2>x = 5/2 , x = - 4/3</h2>
Step-by-step explanation:
6x² - 7x - 20 = 0
Using method of factorization
Rewrite - 7x as a difference
That's
6x² + 8x - 15x - 20 = 0
Factor the expression
That's
2x( 3x + 4) - 5( 3x + 4) = 0
Which is
(2x - 5) (3x + 4) = 0
2x - 5 = 0
2x = 5
Divide both sides by 2
x = 5/2
3x + 4 = 0
3x = - 4
Divide both sides by 3
x = -4/3
Hope this helps you
Answer:
20.
Step-by-step explanation:
Your calculation is correct but the number of times she has to fill or partially fill is 19 + 1 = 20. The last fill is a partial one of 0.2 of the volume of the bucket)
We simply need to plug in x = 4 into x² + 2x
So plugging in x = 4, we get:
4² + 2(4)
Simplifying it, we get:
16 + 2(4)
16 + 8
24
When x = 4, x² + 2x will equal 24.
