12. The square and rectangle shown below have the same perimeter length Show that the length of the rectangle (3x + 1) centimetres

Answers

Lets call the perimeter P and the length of the rectangle l. The first figure is a square with side length 2x + 2 so P = 4(2x + 2) = 8x + 8. For the rectangle, P = 2l + 2(x + 3) = 2l + 2x + 6. These values both equal P so they must equal each other. 8x + 8 = 2l + 2x + 6. Now we have to solve for l.

8x + 8 = 2l + 2x + 6
8x + 2 = 2l + 2x
6x + 2 = 2l
3x + 1 = l

How do you write 72.5% as a fraction in simplest form

What is the fundamental principle of multiplication?

Multiplication is the mathematical operation that is used to determine the product of two or more numbers. If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.

We have to write 72.5% as a fraction in simplest form.

So we put 72.5 over 100

That is (72.5/100)

Now multiply the top and the bottom by 10 to get rid of the decimal, giving;

725/1000

Then divide the top and bottom by like factors,

5 (145/200)

Then another 5,

29 over 40 (29/40)

Hence, the 72.5% as a fraction in simplest form is (29/40)
