Factor completely x2 + 25
Ganezh [65]

Answer:

(x - 5i)(x + 5i)

Step-by-step explanation:

Write this as x^2 + 25.  Solving for x^2, we get x^2 = -25.

Recall that the square root of a negative number is an imaginary one.  √(-25) equals ±5i (there are two roots, one positive and one negative).

Then x = ±5i.

In factored form, the given expression is (x - 5i)(x + 5i).

¾ an hour is 45 minutes

So to have your answers you need to do a cross product :

45 minutes —> 2/3 of a chapter
60 minutes —> X of a chapter

((2/3) • 60) / 45

40/45 = 8/9

Answer : You read 8/9 of a chaper per hour! :)
