Answer:
x=-2 or x=7
Step-by-step explanation:
X²-5X-14=0 find the factors of -14x² which is -7x and +2x
X² -7x + 2x - 14 = 0 factorize
x(x-7) + 2(x-7) = 0
(x+2)(x-7) =0
x+2 = 0 or x-7= 0
x=-2 or x=7

Answer:
-6
Step-by-step explanation:
so the opposite of 6 is -6 they're both exactly 6 from the zero point
Answer:
430.5
Step-by-step explanation:
1. We assume, that the number 525 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 525 is 100%, so we can write it down as 525=100%.
4. We know, that x is 82% of the output value, so we can write it down as x=82%.
5. Now we have two simple equations:
1) 525=100%
2) x=82%
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
525/x=100%/82%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
7. Solution for what is 82% of 525
525/x=100/82
(525/x)*x=(100/82)*x - we multiply both sides of the equation by x
525=1.219512195122*x - we divide both sides of the equation by (1.219512195122) to get x
525/1.219512195122=x
430.5=x
x=430.5
now we have:
82% of 525=430.5
