Answer 1

30-(3+3)=24
24:4=6
6+3=9
Ответ:9,9,6,6.

Answer 2

Finding the sides of a rectangle with a given perimeter

To find the sides of a rectangle when the perimeter is known, we can use the formula for the perimeter of a rectangle, which is given by:

Perimeter = 2 * (Length + Width)

In this case, the perimeter of the rectangle is given as 30 cm, and it is known that one side is larger than the other by 3 cm.

Let's denote the larger side as x and the smaller side as y.

According to the given information, we have the following equations:

x = y + 3 (Equation 1)

Perimeter = 2 * (x + y) = 30 (Equation 2)

We can solve these equations simultaneously to find the values of x and y.

Solving the equations

Substituting Equation 1 into Equation 2, we get:

2 * ((y + 3) + y) = 30

Simplifying the equation:

2 * (2y + 3) = 30

4y + 6 = 30

4y = 24

y = 6

Substituting the value of y back into Equation 1, we can find the value of x:

x = y + 3 = 6 + 3 = 9

Therefore, the sides of the rectangle are 6 cm and 9 cm.

Answer

The sides of the rectangle are 6 cm and 9 cm.
