Write a polynomial that represents the volume of a rectangular prism

Mathematics
1 answer:
sleet_krkn [62]4 years ago
4 0

Answer:

Step-by-step explanation:

volume=length×width×height

V=(4x-3)(x+1)(x+2)

=(4x-3)[x²+2x+x+2]

=(4x-3)(x²+3x+2)

=4x(x²+3x+2)-3(x²+3x+2)

=4x³+12x²+8x-3x²-9x-6

=4x³+9x²-x-6

Sketch a graph of<br> y=3(x − 2)(x + 1) (x – 4)<br><br> ASAPP!
Leno4ka [110]

Answer:

Use the distributive property to multiply 3 by x−2.

y=(3x−6)(x+1)(x−4)

Use the distributive property to multiply 3x−6 by x+1 and combine like terms.  y=(3x  2  −3x−6)(x−4)

Use the distributive property to multiply 3x  2 −3x−6 by x−4 and combine like terms. y =3x  3 −15x  2  +6x+24

Step-by-step explanation:

I also up a link there of a graph. Please tell me if you can open it. Hope this helps! :P

suppose S is between R and T. Use the segment addition postulate to solve for each variable. RS= 7y-4 , ST= y+5 , RT= 28
blagie [28]
RS+ST=RT

RS=7y-4

ST=y+5  using RS and RT in the first equation gives you:

7y-4+y+5=RT  combine like terms on left side

8y+1=RT, and we are told that RT=28 so:

8y+1=28  subtract 1 from both sides

8y=27  divide both sides by 8

y=27/8

(RS=19 5/8, ST=8 3/8, RT=28)
