Answer:

<u>infinitely many solutions</u>

Step-by-step explanation:

The system of equations :

  1. 3x + 2y = 7
  2. -4.5x - 3y = -10.5

Multiplying Equation 1 times 3 and Equation 2 times 2 :

  • 9x + 6y = 21
  • -9x - 6y = -21

Putting the equations in standard form after simplifying :

  1. 6y = -9x + 21 ⇒ <u>y = -1.5x + 3.5</u>
  2. -6y = 9x - 21 ⇒ <u>y = -1.5x + 3.5</u>

<u />

As both equations are the same, the system will have <u>infinitely many solutions</u>.

Answer:

364.8 ft^2.

Step-by-step explanation:

I  assume you want the area of the figure.

Total area = area of the top triangle + area of the trapezium

= 1/2 * base * height + 1/2 * height * ( sum of the parallel sides)

= 1/2 * 18 * 6 + (14/2)( 18 + 26.4)

=  54 + 310.8

= 364.8 ft^2.
