Multiply 1/10 and put the 4 over a 1 and make it 4/1 and multiply
Given is the expression, x² + 12x + n
It says to find value of 'n' that converts it into a Perfect Square Trinomial.
A perfect square trinomial is a quadratic expression which has a single root with multiplicity 2. i.e. it is of the form :- x² + 2bx + b² = (x + b)²
On comparing it with the given expression, we get :-
So 2b = 12 and n = b²
b = 6
and so b² = 6² = 36.
⇒ n = 36
Hence, x² + 12x + 36 = (x + 6)² i.e. n = 36 is the final answer.
Answer:
= 2.3988 x 10^12
Step-by-step explanation:
240,000 million distance to moon = 2.4 × 10^11 (x10)
1 - 0.005 = 0.995 (x10) = 9.995 multiplier.
= 9.995 x 2.4 = 23.988
= 2.3988 x 10^12 distance to Mars
