You find greatest common factor for both the numerator part and the denominator part.

First look at numerator
5x^2 10xy

What is the greatest common factor?

5 and x

So
5x (x + 2y)

[you can multiply them back and see that you get the initial equation. Also, cant simplify x+2y any further so this is correct]

Now the denominator:
X^2 +2xy

Again, find GCF.
It is only x

So,

X(x+2y)

Now what do we have?

5x(x+2y)/ x(x+2y)

You can see that x+2y is present both in numerator snd in denaminator, so you can cancel them out.
You are left with.

5x/x

You can cancel x’s too and you are left with

One of the legs of right triangle measures 16 cm and the other leg measures 2 cm.
Pavlova-9 [17]

Answer:

16.1 cm (nearest tenth)

Step-by-step explanation:

<u>Pythagoras’ Theorem</u>

a^2+b^2=c^2

(where a and b are the legs, and c is the hypotenuse, of a right triangle)

Given:

  • a = 16 cm
  • b = 2 cm

Substitute the given values into the formula and solve for c:

\implies 16^2+2^2=c^2

\implies 256+4=c^2

\implies c^2=260

\implies c=\sqrt{260}

\implies c=2\sqrt{65}

\implies c=16.1 \sf \: cm\:(nearest\:tenth)
