Can someone help asap!?

Step-by-step explanation:

= √33

a^2 x b^2= c^2 remember  a^2 x (b)4^2 = (c)7^2  

                                             a^2 x  16 = 49

                                             a^2 x 16 -16  = 49-16

                                              a^2= 33

To leave in radical form we write down all the square numbers we know.

and see if any numbers go into this as a product but if not (4,9,16,25 etc, as even squares we leave √33

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.
