140 = 10x + 5y
24 = x + y

y is the number of $5 bills     (So 20 $5 bills)

What is the area of the figure in square units?​
igor_vitrenko [27]

Answer:

Area of a Rectangle: l x w

2 x 3 = 6

Area of a Triangle:

\frac{b \times h}{2}

The slanted height of the triangle is 2 and the base of the triangle is also 2 so

\frac{2 \times 2}{2}  \\  \\  \frac{4}{2}  = 2

So to get the area of the figure you add the area of the rectangle plus the area of the triangle.

6+2=8

The area of the figure is 8 units square

3^6

Step-by-step explanation:

9 is actually 3^2, so you have the first one wrong.

The second one is correct, but the third one is not

Since 9 is 3^2, you can write that as (3^2)^3, which is 3^6.
