Question

SUBSTITUTION
p=-4.8 q=3.2
r=3-2p+q^2

Answer 1

R = 3 - 2(-4.8) + 3.2^2

R = 3 + 9.6 + 10.24

R = 22.84

Answer 2

r=16.84

Explanation:

As we know that
`p=-4.8` and
`q=3.2` we can substitute these values in to the equation in order to find the value of r

`r=-3-2p+q^2\\\\r=-3-2(-4.8)+(3.2)^2\\\\r=-3+9.6+10.24\\\\r=16.84`
