If you simplify it more, it would be 
 3x^2+2x-9-4x^2+6x-3
if you simplify it more, the answer is standard form is 
-x^2+8x-12

Write an equation for the statement and then solve
Lunna [17]

Answer:

16.   30 * (30+12)/4*(L)*20

17.  Volume = 6300 * Length of rectangular prism

Step-by-step explanation:

The width of a rectangular prism is <u>30 cm</u>. This is  <u>12 more than one-fourth of the length</u>. Find the  volume of the prism, given the <u>height is 20 cm</u>.

Let L = length of rectangular prisim W = width and H = height

16.  

Volume of a rectangular prism is width * length * height

30 * (30+12)/4*(L)*20

17.  

= 30 * (30+12)1/4(L)*20

= 30 * (42/4)*L * 20

= 600 * 10.5 * L

= 6300 * L

Volume = 6300 * Length of rectangular prism

Help please. Im trying to do my homework but i don't understand how to.
Neko [114]
V = (4/3) pi  r^3

9.  V = (4/3)(3.14)(7.62)^3 = 1852.4  meters^3
10. V = (4/3)(3.14)(33/2)^3 = 18,807.0  inches^3
11. V = (4/3)(3.14)(18.4/2)^3 = 3260.1  feet^3
12. V = (4/3)(3.14)(sqrt3)/2)^3 = 2.7 cm^3
13. C = 2*pi*r ;   24 = 2 * 3.14 * r;   24/6.28 = r ; r = 3.82
   V = (4/3)(3.14)(3.82)^3 = 233.4 in^3
14.V = (4/3)(3.14)(35.8)^3 = 192,095.6  mm^3

I can't read # 15 but follow the steps above.

BCALLE can u help me please

17. RQ is the same as PS.
PS = -1 + 4x
RQ = 3x + 3
-1 + 4x = 3x + 3
4x = 3x + 4
x = 4
Now plug that into RQ.
3(4) + 3 = RQ
15 = RQ

18. Angles G and E are equal to each other.
G = 5x - 9
E = 3x + 11
5x - 9 = 3x + 11
5x = 3x + 20
2x = 20
x = 10
Plug that x into G.
5(10) - 9
41 = G

19. TE and EV are equal to each other.
TE = 4 + 2x
EV = 4x - 4
4 + 2x = 4x - 4
2x = 4x - 8
-2x = -8
x = 4
Plug that into TE.
4 + 2(4)
12 = TE

20. DB and BF are equal.
DB = 5x - 1
BF = 5 + 3x
5x - 1 = 5 + 3x
5x = 6 + 3x
2x = 6
x = 3
Plug that into DB.
5(3) - 1
14 = DB
