Answer:

The length and width of the rectangle are: \mathbf{2x^5y^8\:and\: 12xy^7}

Option A is correct.

Step-by-step explanation:

We are given: Area\:of\:rectangle=Length\times Width

if Area = 24x^6y^{15}we need to find the length and width of rectangle from options given.

Looking at the options, Option B,C and D are incorrect because multiplying the given lengths and widths, the area is not equal to 24x^6y^{15}

Only Option A gives us the result i,e

Area=2x^5y^8\times 12xy^7\\Area=24x^6y^{15}

So, the length and width of the rectangle are: \mathbf{2x^5y^8\:and\: 12xy^7}

Option A is correct.

which graph represents the solution set of the system of inequalities? (is my selected answer correct, if not please help!!)
algol [13]

Answer:

the graph on the right-top

Step-by-step explanation:

Transferring an "x" to the right side in x+y\ge-3, we get y\ge -x-3

The system of inequalities is

\left \{ {{y

We have y=2x+2 - ascending function with a=2, b=2

b=2 shows that ascending function intersects Y-axis is in y=2 - that situation is only on the right-top and left-down. So, we refuse left-top and right-down.

y=-x-3 - descending function with a=-1, b=-3

y<2x+2 is an area below the ascending function and we see that on the left-

y\ge-x-3 is an area above the descending function

On the left-down we have an area above both functions, so we refuse this picture

Right-top is correct

Solve<br><br> y=34x<br> y=-54x+52
jeyben [28]

Answer:

x= 13/22

Step-by-step explanation:

you can substitute y= 34 x on the second equation

34x = -54x +52  add 54x to both sides

34x +54x  = -54x +54x +52

88x = 52  divide both side by 4

22x = 13  divide both sides by 22

x= 13/22
