I need help with a few questions. please help.

For this case we have that the figure is made up of two rectangles and a quarter circle.

By definition we have to:

The area of a rectangle is given by:

Where:

a and b: Are the sides of the rectangle

The area of a circle is given by:

Where:

r: It is the radius of the circle

So:

Rectangle 1:

Rectangle 2:

A quarter of a circle:

Thus, the total area is:

The area of the figure is:

yep

step-by-step explanation:

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40
