Which number is a zero of the function f?
f(x) = x2 - x - 6
F 6
G2
H 3
IO

zeros of the function are −2 and 3

Step-by-step explanation:

there is no -2 so H.3

the thermometer is precise but not accurate

step-by-step explanation:

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.
