Answer:
x-60
Step-by-step explanation:
You have to factor out the quadratic.
You know that one of the factors is x-40.
To factor:
Find a number that when added to -40, gives you -100, and also when multiplied, gives you 2400.
That such number is -60.
Add an x before it, and you get (x-60)
By Sine Rule,
x/sin30° = 8/sin90°
x/0.5 = 8/1
So x = 4.
The answer is A. because if she read 4 times as much, p multiplied by 4= 40
