Answer:

if the sum of any 2 sides is equal to or less than the third side it is Not a triangle.

So A :- we have 2+4 = 6 so its not a triangle.

also D is not a triangle because 8+3 < 12

what about B and C?

Answer:

x / 4

Step-by-step explanation:

25 %

= 25 / 100

= 1 / 4

25 % of x

= ( 1 / 4 ) * x

= ( 1 * x ) / 4

= x / 4

Note : -

% need to converted to fraction / simplest form.

" of " means " multiply " in this situation.

Answer:

4^0

Step-by-step explanation:

The rules of exponents are ...

(a^b)(a^c) = a^(b+c)

(a^b)/(a^c) = a^(b-c)

So, your expression simplifies to ...

$4^5\times4^{-7}\div4^{-2}=4^{5-7-(-2)}=\boxed{4^0}$

Type the correct answer in the box. Use numerals instead of words. If necessary, use / for the fraction bar.

From given picture we can see that X is mid point of line PQ

So PQ=2PX

From given picture we can see that Y is mid point of line PR

So PR=2PY

Now consider triangles PRQ and PYX

Sides PQ and PX has same ratio as of sides PR and PY (as calculated above)

angle XPY= angle QPR (common angle)

Hence triangles PRQ and PYX are similar.

We know that ratio of the sides of similar triangles is always equal so we can write:

$\frac{PQ}{PX} = \frac{QR}{XY}$

Plug the given values QR=8 and PQ=2PX

$\frac{2PX}{PX} = \frac{8}{XY}$

$\frac{2}{1} = \frac{8}{XY}$

$2 = \frac{8}{XY}$

$XY = \frac{8}{2}$

$XY = 4$

Hence final answer is XY = 4 units.
