Answer:

A=(2x^{2}+9x-18)\ m^{2}

Step-by-step explanation:

Let

L-----> the length of the concert hall

W----> the width of the concert hall

we know that

The area of a rectangle ( concert hall) is equal to

A=LW

we have

L=(x+6)\ m

W=(2x-3)\ m

substitute the values

A=(x+6)(2x-3)\\ \\A=2x^{2} -3x+12x-18\\ \\A=(2x^{2}+9x-18)\ m^{2}

Change these equations into the equations of linear functions.
\left \{ {{4x-2y=22} \atop {6x+9y=-3}} \right. \\ \\&#10; \left \{ {{-2y=-4x+22} \atop {9y=-6x-3}} \right. \\ \\&#10; \left \{ {{y=2x-11} \atop {y=-\frac{2}{3}x-\frac{1}{3}}} \right.

Draw function graphs and read coordinates of the intersection.

Dora bought a bottle of nail polish that was marked down by 20 percent from its original price of $4.50. Including a 9 percent s
igomit [66]

Answer:

3.92$

Step-by-step explanation:

The first step is to deduct 20% of 4.50 from 4.50.

20% of 4.50 is 0.2 x 4.50 = .90

4.50 - 0.90 = 3.60

That's the new price without the sales tax.

Now we need to add 9% of 3.60 to 3.60 to get the final cost.

9% of 3.60 is .09 x 3.60 = 0.32

3.60 + .32 = $3.92

Hope it helps.. If yes mark me BRAINLIEST

Tysm!

If integral 1 to 5 f(x)dx =36/15 what is the value of integral from 5 to 1 f(x)dx?<br><br><br>​
fredd [130]

Answer:

  -36/15

Step-by-step explanation:

If the indefinite integral of f(x)dx is F(x), then your integral from 1 to 5 is ...

  F(5) -F(1) = 36/15

The integral in the reverse direction is ...

  F(1) -F(5) = -(F(5) -F(1)) = -36/15
