Answer:
Given equation have two solutions.
x = 
Right option is (D)
Step-by-step explanation:
We have given,

we can rewrite this equation in the form given as:
6x² + 40 + 31x = 0
or 6x² + 31x + 40 = 0
On solving this quadratic equation, we get :
x = 
That means, given equation have two solutions.

Answer:
2500 grams
Step-by-step explanation:
convert 2.5 kilograms to grams by multiplying by 1000
= 2.5×1000= 2500grams
Since x can be any value as long as the denominator equals 0 (it doesn't matter if it's positive or negative), we have to figure out when x^2=0, which is when x=0. Therefore, the domain is (-inf, 0) U (0, inf)
