choice a is correct answer.
given expression is :
we have to represent above expression in factored form.
as we have noticed that the expression contains the multiples of 3.
taking 3 as common from given expression,we get
now, spit the middle term of above expression so that the product of two terms should be 8 and their sum be 6.
making two groups and taking two terms as common,we get
taking (x+4) as common,we get
3(x+4)(x+2) which is the factored form of 3x²+18x+24.
the correct answer is 8. but in the option there is no option with answer 8
the given expression is,
x - 9 = -6 + 5
rhs = -6 + 5 = -1
lhs = x -9
lhs = rhs
therefore x - 9 = -1
x = -1 + 9 = 8
therefore the correct answer is 8.
there is no option with correct answer. so we cant
in complex plane we can see a+bi as the point (a,b).
so 5-2i can be seen as (5,-2)
and 8+i can be seen as (8,1)
now we can use the distance formula to find the distance between the two points .
distance formula is
plugging the respective values we get
so distance is
