#1, your middle term is x , thus A
#2 D
#3 B
How are you doing these, so far they are all wrong
(4p2)(p4)
= 4p^2  16p  2p + 8
= 4p^2  18p + 8
#4
A = 2πr^2 + 2πrh
= 2π(3x2)^2 + 2π(3x2)(x+3)
= 2π[ 9x^2  6x  6x + 4 + 3x^2 + 9x  2x  6]
= 2π[12x^2  5x  2] ,
which is D
#5
(2x^2+4x3)(3x+1)
= 6x^3 + 2x^2 + 12x^2 + 4x  9x  3
= 6x^3 + 14x^2  5x  3
I think you will need more practise with these.
