(20 + 12) - 8, since the question states n is EIGHT less than the sum of 20 and 12.
Answer:
7.065 m ^ 2
8.935 m ^ 2
Step-by-step explanation:
The first thing is to calculate the surface of each one, that is, the area
For the room that is square, each side measures 4m, therefore:
As = 4 * 4 = 16 m ^ 2
The area of the carpet is that of a circle, that its area is the number pi times the radius squared, we know that the radius is half the diameter, therefore r = 3/2 = 1.5 m
replacing in the area formula
Ac = pi * r ^ 2 = 3.14 * 1.5 ^ 2
Ac = 7.065 m ^ 2
In other words, the area covered by the carpet is 7,065 m ^ 2 and the area not covered would be the subtraction between the area of the room minus the area of the carpet, that is:
16 m ^ 2 - 7.065 m ^ 2 = 8.935 m ^ 2
8.935 m ^ 2 would be the area that the carpet does not subside.

➪x= 13
Step-by-step explanation:
49+59+5x+7=180
115+5x= 180
5x = 180-115
5x= 65
x= 65/5
x= 13
