It is a number that has a variable and the variable can change to anything that you multiply by the factor it sits with. So basically it’s a number (3) that multiplies by whatever y equals to.

Answer:

3y means 3 * y

Step-by-step explanation:

I think it is written as 3y instead of 3*y or 3 x y because, 3*y is a bit too cluttered, and 3xy or 3 x y means (Three times X times Y) because X is its own variable.

In other words, 3y means 3 times y

Which of the following best describes the equation below?
Reika [66]
4(x + 9) + 5x = 9x - 36

=> 4x + 36 + 5x = 9x - 36

=> 9x + 36 = 9x - 36

=> 9x - 9x = -36 - 36

=> 0 = -72

You can see that the equation doesn't hold true.

So there is no solution for this equation.

Find the area of the trapezoid.<br> Answer options: 8sqrt2, 4sqrt3, 12.0, 16sqrt2
Elis [28]

Answer:

=  8sqrt2

Step-by-step explanation:

Area of a trapezium is given by the formula;

1/2(a+b)h ;

Where a and b are the parallel sides and h is the perpendicular height.

a = 3 cm, b= 5 cm

To get; h, we use the Pythagoras theorem;

h² = 3² - 1²

   h² = 8

h = √8

  = √4√2

 = 2√2

Thus;

Area = 1/2(3 +5) 2√2

         = 1/2 ×8 × 2√2

       <u>  = 8√2 cm² or  8sqrt2 cm²</u>
