Answer:

18x+32

Step-by-step explanation:

Perimeter is the total distance around a shape and can be found by calculating the sum of a shape's sides.

In this case, we are given a parallelogram, a quadrilateral with two pairs of parallel sides. Thus, the formula for a parallelogram's perimeter is as follows:

P=2(a+b)

Substitute the variables in the formula for the expressions on the parallel lines:

a=3x+6

b=6x+10

P=2(3x+6+6x+10)

Distribute the 2 into each term:

P=6x+12+12x+20

P=18x+32

Answer:

<h2>18x + 32</h2>

Step-by-step explanation:

Perimeter = 3x + 6 + 6x + 10 + 6x + 10 + 3x + 6

= 18x + 32...ans

Tickets for a concert are $40 for main-floor seats and $25 for upper level seats. A total of 2000 concert tickets were sold. The
Tems11 [23]

Step-by-step explanation:

<u>to show how many tickets were sold:</u>

x = upper floor tickets

y = main floor tickets

x + y = 2000

<u>to show total amount of revenue:</u>

25x + 40y = 62,000

<u>Finding answer using both equations:</u>

x + y = 2000

multiply each side by 25

25x + 25y = 2000 × 25

25x + 25y = 50,000

25x + 40y = 62,000

-

25x + 25y = 50,000

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

15y = 12,000

^ this is column subtraction

<em>^ this column subtraction is done to isolate y so we can work with one value rather than 2</em>

15y = 12,000

divide each side by 15

12,000 ÷ 15 = 800

y = 800

x + y = 2000

x + 800 = 2000

x = 1200

Therefore 1200 upper-level tickets were sold

800 main floor tickets were sold

Which is the graph of f(x) = (x - 1)(x + 4)?
zheka24 [161]

You can determine this by finding zeros of quadratic function,

(x-1)(x+4)=0\implies x_1=1, x_2=-4.

Which eliminates first and third option.

Now we have up and down parabolas left.

If we factor (x-1)(x+4)=x^2+4x+\dots we find that the coefficient before x^2 determines how it is turned, since its positive its an upward turned parabola hence the answer is the last graph.

Hope this helps.
