A sandbox has a volume of 648 cubic feet. what is the volume, in cubic yards, of the sandbox?

1 answer:

6 0

We know that

1 cubic yards equals to--------------> 27 cubic feet
then
I apply a rule of three
if 1 cubic yards ------------------- 27 ft³
X----------------------------------> 648 ft³
X=648/27=24 cubic yards

the answer is 24 cubic yards

$4xy(2)+4xy^2$

Factor 4xy out of $4xy^2$

4xy(2) + 4xy(y)

Factor 4 x y out of 4 x y ( 2 ) + 4 x y ( y ) .

A) 2x + y - 12 = 0 x + y + 3 = 0

AVprozaik [17]

Answer:

x=15 and y= -18

Step-by-step explanation:

$2x + y - 12 = 0$ Equation 1

$x + y + 3 = 0$ Equation 2

From two given equations, we can find the value of both x and y by finding the value of one variable from any one of the two equations in terms of other variable and putting it to other equation.

Solving equation 1

Finding 'y' in terms of 'x' $2x+y=12\\y=12-2x$ Equation 3

Putting above equation in equation 3 in 2

$x + y + 3 = 0$

$x+12-2x+3=0$

$x=15$

Putting value of 'x' in equation 3 to find the value of 'y'

$y=12-2(15)\\y=12-30\\y= -18$

Consider the leading term of the polynomial function. What is the end behavior of the graph? Describe the end behavior and provi

Nookie1986 [14]

The leading term is -3x^5. The end behavior of any function is the behavior that the highest powered term has as x approaches ±oo.

In this case because the highest order term is -3x^5, as x approaches -oo, y approaches +oo. And as x approaches +oo, y approaches -oo.
