Answer:

(6 {x}^{2}   - 7x - 5) \:  {units}^{2}

Step-by-step explanation:

Area of rectangle = Product of sides

= (2x + 1) \times (3x - 5) \\  = 2x(3x - 5) + 1(3x - 5) \\  = 6 {x}^{2} - 10x + 3x - 5 \\ area \: of \: rectangle \:  \\  = (6 {x}^{2}   - 7x - 5) \:  {units}^{2}

If b = 3, then 3x + y = 1 and bx - y = 3 are parallel.<br> True or <br> False ...?
Ulleksa [173]
I am absolutely sure that the task <span> b = 3, then 3x + y = 1 and bx - y = 3 is NOT parallel, which means that the statement represented above is FALSE.
To make sure you can check it using : </span>y=-3x+1&#10;&#10;y=3x-3 Hope now it's obvious. Regards!
