Answer:
$11000 at 4% and $4000 at 8%
Step-by-step explanation:
5√7 + 12√6 - 10√7 - 5√6
Write it like this:
(12√6 - 5√6) + (5√7 - 10√7),
as the 12 and 5 are both being multiplied by √6, they can be added or subtracted and its the same with 5 and 10, so it becomes:
7√6 - 5√7
You should leave it like this.
Answer:
What math is this?
Step-by-step explanation:
Answer:
<h2>The area of the total figure is around 535.43 square centimeters.</h2>
Step-by-step explanation:
In the image attached, you can notice that all rectangles have a base of 20 centimeters.
Also, each side of the equilaterals triangles is 8 centimeters.
Notice that the height of each rectangle is equal to a side of a triangle.
Using all given vales, the area of each rectangle is

The area of all rectangles is
, because there are three rectangles in total.
The area of each triangle is

The area of both triangles is

Now, the area of the whole figure is the sum of the area of triangles and rectangles

Therefore, the area of the total figure is around 535.43 square centimeters.
