We can cosider this to be  a difference of 2 squares  so 

4x^4 - 9x^2 = (2x^2 - 3x)(2x^2 + 3x)   so D is one answer

also we could take x^2  out and get 
x^2(4x^2 - 9)  = C

48% of 8? 3% of 119? 26% of 280?
OLga [1]
X% of y
x%=x/100
'of' means multiply
x% of y=x/100 times y so

48% of 8=48/100 times 8=384/100=3.84

3% of 119=3/100 times 119=357/100=3.57

26% of 280=26/100 times 280=7280/100=72.8
