B) 6x^3+14x+5x-3
C) 6x^3+14x^2-5x-3
D) 6x^3-10x^2-5x-3

Answer 1

#1, your middle term is -x , thus A

#2 D

#3 B
How are you doing these, so far they are all wrong
(4p-2)(p-4)
= 4p^2 - 16p - 2p + 8
= 4p^2 - 18p + 8

#4
A = 2πr^2 + 2πrh
= 2π(3x-2)^2 + 2π(3x-2)(x+3)
= 2π[ 9x^2 - 6x - 6x + 4 + 3x^2 + 9x - 2x - 6]
= 2π[12x^2 - 5x - 2] ,
which is D

#5
(2x^2+4x-3)(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.

Answer 40

I’m so scared for the exams cause i cheated my whole way thru the semester lol, I failed last years math exam😭 and had to do summer school for math and then had to retest so

Answer 41

yeesh, can't you though, I'm in honors algebra and I only understood some of the work, just hope I don't have to do summer school, although I really don't see the point of it since schools usually reteach subjects once you get back
