Question

Verify the property p×(q+r)=(p×r)+(p×r) by taking




p=5/2,q= -1/5and r = -3/4​

Answer 1

Step-by-step explanation:

Given,

P(−2,2)

Q(2,2)

R(2,7)

⇒∣PQ∣=

(−2−2)

2

+(2−2)

2

=

(4)

2

=4units

⇒∣PR∣=

(−2−2)

2

+(2−7)

2

=

(4)

2

+5

2

=

16+25

=

41

units

⇒∣PQ∣=

(2−2)

2

+(2−7)

2

=

(5)

2

=5units

we can clearly see that

⇒∣PR∣

2

=∣PQ∣

2

+∣QR∣

2

( Pythagoras theorem )

since ∣PQ∣

2

=16

and ∣QR∣

2

=25

∴∣PQ∣

2

+∣QR∣

2

=16+25=41

and we have ∣PR∣=

41

∴∣PR∣

2

=41units

Hence, we have 'PR' as the hypotenuse and PQ and QR are the other two legs of the right angled triangle.

hope this helped

i dont know these maths

found this on google

hopefully u find this helpful
