Pythagorean theorem help plz i really need help plz i dont really get it cuz i forgot

7.62 the answer is already rounded.

Step-by-step explanation:

C= the square root of A² + B²

c= square root of 7²+3²= 7.615773106=7.62

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.

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.
