45
Step-by-step explanation:
The answer to this problem is D!
Answer:
Step-by-step explanation:
Since the slope is -5 is either C or D. Let's replace 
in either to see what we get.
C: 
Nope.
D: 
Good!
3(3x+4)(2x+5)
Because you factor out the 3 and then factor 6x^2+23x+20
That becomes (6x^2+8x)+(15x+20)
Factor out a two from the left and five from the right.
That makes 2x(3x+4) + 5(3x+4)
That becomes (3x+4)(2x+5)
Then put the three back in front.
