3 0

Step-by-step explanation:

(a): 5x^2 + 25 = 5 * x^2 + 5 * 5 = 5(x^2 + 5).

(b): 2x^2 - 3x - 2 = 2x^2 - 4x + x - 2

= 2x(x - 2) + 1(x - 2) = (2x + 1)(x - 2).

A pilot can see the runway she is about to land on directly ahead. When looking at each end of the runway, the angles of depress
Lostsunrise [7]
First, we get the length of the runway in which the pilot had seen a 45° by using the trigonometric formula of tangent. 
                                    tan 45° = 1,500 / x
The value of x from the equation is 1500 ft. 
We do the same for the 42°
                                   tan 42° = 1,500 / y
The value of y is equal to 1665.92 ft. To determine the length of the runway, we subtract the lengths calculated and this will give us an answer of 165.92 ft.

How to check that a number is divisible by 3 or not?? Need a best shortcut!!
Lilit [14]
If your number is quite large, like 3 digit or higher than that, then calculate the sum of their digits, if they will be divisible by 3, then the number is divisible, otherwise not.

For example. - "11055" 
Here, sum of digits = 1 + 1 + 0 + 5 + 5 = 12
As 12/3 = 4 (Divisible)

In short, This number would be divisible.

Hope this helps!
