How do you rearrange fractions

1 answer:

4 0

For ex:

U have 4/8 - 6/2 u would probably have to use KCF- Keep Change Flip
So then it’ll be 4/8 + 2/6
U kept the 4/8 then u changed the subtraction to addition and u flipped the 2 to the numerator and the 6 denominator.
Idk my dude this is what I can think of

The length of PR is 4.4 units.

Explanation:

It is given that the length of the hypotenuse is 10 units.

Also, the angle of R is 64°

To find the length of PR, we shall use the cosine formula,

$\cos \theta=\frac{a d j}{h y p}$

Here, $\theta=64$ , adj = PR and hyp = 10

Substituting these values in the formula, we get,

$\cos 64=\frac{P R}{10}$

Multiplying both sides by 10, we get,

$10*\cos 64={P R}$

Substituting the value for cos 64, we get,

$10*0.438={P R}$

Multiplying, we have,

$4.38=PR$

Rounding off, we get,

$PR=4.4$

Thus, the length of PR is 4.4 units.

8u/u^2-18u+81 subtract 72/u^2-18u+81

Karo-lina-s [1.5K]

Your question is:
$\frac{8u}{u^2-18u+81} -\frac{72}{u^2-18u+81}$
Then, the above formula equate:

$\frac{8u-72}{u^2-18u+81}$
Factor out 8 from the numerator we get:
$\frac{u-9}{u^2-18u+81}$
Factorization of the denominator:
$\frac{u-9}{(u-9)^2}$
Simplifying the numerator and the denominator by (u-9) we get:
$\frac{1}{(u-9)}$
