Answer:
2x^2 - 5x - 3 = (2x + 1) (x - 3) IS CORRECT

Step-by-step explanation:

F O I L : Firsts Outsides Insides Lasts

— (2x+ 1) (x - 3) Multiply 2x with x = 2x^2

— (2x + 1) (x - 3) Multiply 1 with -3 = -3

— (2x + 1) (x - 3) Multiply -3 with 2x = -5x


(2x + 1) (x - 3) = 2x^2 - 5x - 3

Anna11 [10]

The length of the third side of the quadrilateral is 7.5 cm.

<h3>Quadrilateral</h3>

A quadrilateral is a polygon that has four sides and four angles. The sum of interior angles in a quadrilateral is 360°. Types of quadrilateral are square, rectangle, rhombus, kite and so on.

Let x represent the length of the third side, hence:

x = 5 + (5 * sin(20)) + (5 * sin(10)) = 7.5 cm

The length of the third side of the quadrilateral is 7.5 cm.

5) A theatre can be rented for different hours. The cost is $100 for deposit and $200 per hour. Write a function rule to find th
IgorLugansk [536]

Answer:

Step-by-step explanation:

Since the cost is $100 for deposit and $200 per hour, the function rule to find the total cost of renting the theatre for 'n' hours will be:

= 100 + 200(n)

= 100 + 200n

The total cost if you rented the theatre for 4 hours will be gotten by replacing n with 4. This will be:

= 100 + 200n

= 100 + 200(4)

= 100 + 800

= $900
