Answer:

I think it's A because.

Step-by-step explanation:

A rectangular box has a volume x^3-64 cubic inches. If the height of the box x-4 inches, what is the area of the base of the box
Zanzabum

Answer:

\purple{ \bold{ \therefore \: A_{base} = {x}^{2}  + 4x +  16}}

Step-by-step explanation:

\because \: V_{box} = A_{base} \times height  \\  \\ \therefore \: A_{base} =  \frac{V_{box}}{height}  \\  \\ \therefore \: A_{base} =  \frac{ {x}^{3}  - 64}{(x - 4)}   \\  \\  \therefore \: A_{base} =  \frac{ {x}^{3}  -  {4}^{3} }{(x - 4)}   \\  \\  \therefore \: A_{base} =  \frac{ \cancel{ ({x}  -  {4})}( {x}^{2}  + 4x +  {4}^{2}  )}{\cancel{ ({x}  -  {4})}}  \\  \\ \purple{ \bold{ \therefore \: A_{base} = {x}^{2}  + 4x +  16}}

14.What is the solution of the system?
Archy [21]

Answer:

14.  x=-2.5,  y = -7

15.  x=28  y = -20

Step-by-step explanation:

14.  Let's solve this system by elimination.  Multiply the first equation by -1.

-1*(4x-y)= -1*(- 3)

-4x +y = 3

Then add this to the second equation.

-4x+y = 3

6x-y= - 8

--------------

2x   = -5


Divide each side by 2

x = -2.5

We still need to find y

-4x+y =3

-4(-2.5) + y =3

10 +y =3

Subtract 10 from each side.

y = 3-10

y = -7


15.I will again use elimination to solve this system, because using substitution will give me fractions which are harder to work with.   I will elimiate the y variable.  Multiply the first equation by 11

11( 5x+6y)= 11*20

55x+66y = 220

Multiply the second equation by -6

-6(9x+11y)=32*(-6)

-54x-66y = -192


Add the modified equations together.

55x+66y = 220

-54x-66y = -192

---------------------------

x = 28

We still need to solve for y

5x+6y = 20

5*28 + 6y =20

140 + 6y = 20

Subtract 140 from each side

6y = -120

Divide by 6

y = -20
