Y=p2 +gr
Find y when p=-5, q=3 and r=-7.
Write p in terms of q, r and y.

4

p= √(y-qr)

Step-by-step explanation:

y=p² +qr

p= -5, q=3, r= -7

p²= y - qr

p= √(y-qr)

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.

the answer is b.

step-by-step explanation:

identity property is where 0+whatever number=whatever number. basically 0+ a number.
