Which is the dependent variable when 3x = y?

Andrej [43]

Answer:

A dependent variable is a variable (often denoted by y ) whose value depends on that of another. so it is the variable that changes depending on the numbers beside it.

Please how to answer.

vivado [14]

Answer:

Blue Rectangle: 135 mm²

Blue Triangle: 45 mm²

Not sure if you need this but the Total Square: 225 mm²

Step-by-step explanation:

Area of a rectangle: length x width

Area of a triangle: $\frac{1}{2}$ x base x height

First find the area of the blue rectangle.

Length = 15 mm

Width = 9 mm

Area = 135 mm²

Now find the area of the blue triangle:

Base = 6 mm (because the bottom is 15 total and you subtract the 9)

Height = 15 mm

Area = 45 mm²

Hope it helps!
