Answer:
3x² + 6x - 24 = 0
(3x - 6)(x + 4) = 0
x = -4 , x = 2 when y = 0
Step-by-step explanation:
3x² + 6x - 24 = 0
(3x - 6)(x + 4) = 0
Means
3x - 6 = 0 ⇒ 3x = 6 ⇒ x = 6 ÷ 3 = 2
x + 4 = 0 ⇒ x = -4
The Parabola which represents the quadratic equation intersects x-axis at
points (2 , 0) and (-4 , 0)

Answer:</em></u>
The number is 40
<u><em>
Explanation:</em></u>
Assume that the number we are looking for is x.
We know that 55% of the number x is 22.
This means that:
55% of x = 22
55% * x = 22
0.55x = 22
<u>Now, we will simply solve for x as follows:</u>
0.55x = 22
x = </span>

Answer:
Each student must raise $14.90
Step-by-step explanation:
This is actually fairly easy to figure out (at least this part) all you do is 447/30 and then you get your 14.9 (14.90)
m = 14.90
30m = 447
Answer:
x is greater than or equal to 3. x <u>></u> 3
Step-by-step explanation:
360 - .2(360) = 288 is 100% of 360,
288*.9 = 259.2
