Question

Evaluate the following for p=-1, Q=-3,r =7: c.) p+q-pq+r^2​

Answer 1

Answer:

42 is the answer

Step-by-step explanation:

p= -1

Q= -3

r= 7

p+q-pq+r^2

-1+(-3) - (-1)(-3)+ 7^2

-1-3-(3)+ 49

-7+49

42

____________________________________________

■ The values are given as:-

▪︎p=-1

▪︎q=-3

▪︎r=7

_____________________________________________

■ Now, Putting these values

in the given equation,

$= p + q - pq + {r}^{2}$

$= ( - 1) + ( - 3) - ( - 1) \times ( - 3) + ({7})^{2}$

$= - 1 - 3 - 3 + 49$

$= - 7 + 49$

$= 42$
