Answer:
First choice is the correct one

Explanation:
The given is:
[(x+5) / (x+2)] - [(x+1) / x(x+2)]
First, we will need to have a common denominator and then we will solve the subtraction normally. To get a common denominator, we will have to multiply both numerator and denominator of first term by x.

Therefore:
[(x+5) / (x+2)] - [(x+1) / x(x+2)] = [x(x+5) / x(x+2)] - [(x+1) / x(x+2)]
                                                 = [x(x+5)-(x+1)] / [x(x+2)]
                                                 = (x^2 + 5x - x - 1) / [x(x+2)]
                                                 = [(x^2 + 4x - 1)] / [x(x+2)]

Hope this helps :)

Find the measure of two complementary angles, a and b, if m a = 7x + 4 and m b =4x + 9
VashaNatasha [74]
Complentary angles add to 90 degrees
a and b are complentary
a+b=90

a=7x+4
b=4x+9
so
7x+4+4x+9=90
combine like terms
11x+13=90
minus 13 both sides
11x=77
divide both sides by 11
x=7

m a =7x+4=7(7)+4=49+4=53
m b=4x+9=4(7)+9=28+9=37

angle a measures 53 degrees
angle b measures 37 degrees

On the first day of vacation, you read one-quarter of a novel. On the second day, you read half of the remaining pages. On the t
OverLord2011 [107]

The computation shows that the number of pages is 320.

The number of pages read in this second day will be 120.

<h3>How to illustrate the information?</h3>

Fraction read on first day = 1/4

Fraction news on second day = 1/2 × 3/4 = 3/8

Fraction read on last day = 1 - (1/4 + 3/8) =3/8

The number of pages that the book has will be:

= 3/8 × x = 120

0.375x = 120

x = 120/0.375

x = 320

The number of pages is 320.

b. The number of pages read on this second day will be:

= 3/8 × 320

= 120
