(x^4)(3x^3-2)(4x^2+5x)
=(3x^7-2x^4)(4x^2+5x)
=12x^9+15x^8-8x^6-10x^5
answer: 12x^9+15x^8-8x^6-10x^5

Answer:
SA=390
Step-by-step explanation:
9*14=126
126+126=252
14*3=42
42+42=84
9*3=27
27+27=54
252+84+54=390
 
        
             
        
        
        
Answer and Step-by-step explanation:
1st box:
0, -3
2nd box
-2, -9/4
3rd box:
2, -3/2
4th box:
4, 0
Btw 0, -2, 2, 4 are in the x-coordinate column if you didn’t know, and 1, -9/4, -3/2 are in the y-coordinate column
Basically to solve if you plug in 0 into x, so basically it’s 3(0)-4y=12, which you simplify gives you 0-4y=12, subtract 0 from 12 which is 12 and then do 12 divided by -4 and then you get y = -3 and that’s how you get the box answer
Idk how to the rest srry lol!
 
        
             
        
        
        
Answer:
Volume=1232cm Surface area=660cm
Step-by-step explanation:
Volume=π x r² x t
 =22/7 x 7 x 7 x 8
 =1232cm
Surface area=2 x π x r x (r+t)
 =2 x 22/7 x 7 x (7+8)
 =44 x 15
 =660cm
SORRY IF I AM WRONG, I'M TRYING MY BEST
