1) 12 cm
2) 38
3) 20
4) 40
Each cm is equivalent to 12.5m. So what you can do I just divide all of them by 12.5 to get the answers above.
Hey buddy I got your answer
Its 105
Answer:

Step-by-step explanation:
Consider the given equation

Factor form of a parabola: It displays the x-intercepts.
.... (1)
where, a is a constant and, p and q are x-intercepts.
So, we need to find the factored form of the given equation.
Splinting the middle term we get


.... (2)
On comparing (1) and (2) we get

It means x-intercepts of the given parabola are 4 and 2.
Therefore, equivalent forms of the equation is y=(x-4)(x-2).
Answer:
x = 10
Step-by-step explanation:
x + 10 = 20
=> x = 20 - 10
=> x = 10
