Answer:

Step-by-step explanation:

Substitute:

$x^{0.5} = y$

Then the expression becomes:

$(\dfrac{1+y^3}{1-y+y^2}-y) \dfrac{1-y^2}{1-y} -y=\\$
$(\dfrac{(1+y)(1-y+y^2)}{1-y+y^2}-y) \dfrac{(1-y)(1+y)}{1-y} -y=$
$(1+y-y)(1+y)-y=$
$1(1+y)-y=$
$1+y-y=$
1

The result is 1 regardless the value of x other than 1.

40° 87° Xº Q Image not to scale 38° Calculate the missing internal angle x.

bagirrra123 [75]

Q = 87 + 40

Q = 127

X + 127 + 38 = 180

X = 180 - 127 - 38

X = 15

Therefore we say X is 15
