Answer:
8x^3+60x^2+150x+125
Step-by-step explanation:
(2x+5)^3=(2x+5)(2x+5)^2 =
(2x+5)(4x^2 +2*2x*5+25)=
(2x+5)(4x^2 +20x+25)=
(2x*4x^2 +2x*20x+2x*25+5*4x^2+5*20x+5*25)=
8x^3+40x^2+50x+20x^2 +100x+125=
1.2%
I did math
its the second answer!
y = 2/3x + 1
b= y-intercept = 1
slope = 2 up 3 over = 2/3
y=y cause it is
the answer is -23-3x
