Question

If p =3,q= -5,r=4 what is the value of pq+qr+rp

Answer 1

Answer:

-23

Step-by-step explanation:

P= 3

Q= -5

PQ = 3 x -5

= -15

qr= -5 x 4

= -20

rp = 4 x 3

=12

All together

-15 + -20 +12

=(-35) + 12

-23

Answer 2

Your answer is -23.

Given :

p = 3 , q = -5 ,r = 4.

Solution :

pq + qr +rp = (3)(-5) + (-5)(4) + (4)(3)

= (-15) + (-20) + (12)

= - 23
