What is the standard form of (x+5)(x+5)

x² + 10x + 25

Step-by-step explanation:

Given

(x + 5)(x + 5)

Each term in the second factor is multiplied by each term in the first factor, that is

x(x + 5) + 5(x + 5) ← distribute both parenthesis

= x² + 5x + 5x + 25 ← collect like terms

= x² + 10x + 25 ← in standard form

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.
