Question

If p is equal to minus 2 q is equal to 3 find 3 p square q

Answer 1

Answer:

p = -2q = 3

to find -> 3p^2q

-2q = 3

so,

q = -3/2

since,

p= -2q

so,

p= -2×-3/2

so,

p= 3

hence,

3p^2q = 3×(3×3)×-3/2

= -81/2

= -40.5

Answer 2

Answer:

3p²q = -40.5

Step-by-step explanation:

p = -2q = 3

from above ,

p = 3 & -2q =3

p = 3 & q = -3/2

now,

3p²q = 3(3)²(-3/2)

3p²q = 3(9)(-3/2)

3p²q = (27 × -3)/2

3p²q = -81/2

3p²q = -40.5
