Decompose the rectangle along the diagonal and recompose the two pieces to make a different shape, then five different ways are shown.
<h3>Further explanation
</h3>
Area is the number of squares inside a two-dimensional shape.
Here are two important principles for finding area:
- If two figures can be placed one on top of the other, then they have the same area so that they match up exactly.
- We can decompose a figure (break a figure into pieces) and rearrange the pieces (move the pieces around) to find its area.
A rectangle has two diagonals. Each one is a line segment drawn between the opposite vertices (corners) of the rectangle. For rectangle, shapes can be decomposed and rearranged back to rectangles to find the area. When decomposing and rearranging shapes the area of the polygon does not change.
The rectangle is shown in the picture below. After decompose the rectangle along the diagonal, we can varied the pieces to make various different shape. Picture below also shown the five different ways pieces from the rectangle.

Answer:
-2
this eq. can be simplified to -
y = 5 - 2x
we know that the coefficient of x is the slope
therefore , -2 is the slope
Answer:
W=50M
Step-by-step explanation:
Since there are 18 workers per 900 minerals, divide out to simplify.
STARTING EQUATION: 900m=18w
SIMPLIFY: divide both sides by 18.
SIMPLIFIED: 50m=1w
There is your answer!
Answer: $210.75
Explanation: You multiply the price of the object by how many they buy.
So for the beams you calculate 3 x 45.25 and get 135.75. For the screws you multiply 6 x 12.50 and that equals 75. Then, for the total price you add the two together, so 135.75 + 75 = 210.75
Another way to do it is (3 x 45.25) + (6 x 12.50) = 210.75
