<span>In the question "Which equation results from taking the square root of both sides of (x – 9)2 = 81?" The correct answer is x - 9 = +/- 9. Taking the square root of both sides of the equation (x - 9)^2 = 81 will give: sqrt(x - 9)^2 = sqrt(81) x - 9 = +/- 9 Solving the equation results in two equation: x - 9 = 9 and x - 9 = -9 x = 9 + 9 and x = -9 + 9 x = 18 and x = 0</span>

tom rides the bus part of the way to school and then he walks the rest pf the way. he walks five minutes longer than he rides. t
ruslelena [56]

Answer:

16 minutes

Step-by-step explanation:

Tom walks for 5 minutes longer than he rides. To figure out the answer, start by subtracting 5:

27 - 5 = 22

Now that you have done this, divide 22 by 2:

22/2 = 11

Now you know that he rode the bus for 11 minutes, and you can add five to the other 11 minutes to know how long he walked:

11 + 5 = 16.

The area of the figure is 45 sq.mi and the perimeter is 23.5354 mi.

<h3>What is Area ?</h3>

Area is the space occupied by a two dimensional object,

The area and perimeter of the given shape can be determined by dividing it into basic shapes.

The area and the perimeter of the shape given = Area of the rectangle +Area of upper triangle - Area of two small triangles at the bottom

Area of rectangle = 5 mi * 9 mi = 45 sq.mi

Area of upper Triangle = (1/2) *9*3 = 27/2 sq.mi

Area of small Triangle = (1/2) * 3*6 = 9 sq.mi

Area of other small Triangle = (1/2)*3*3 = 9/2 sq.mi

Area of the figure = 45 +13.5 -9-4.5

Area of the figure =  45 sq.mi

Similarly for Perimeter = Perimeter of the rectangle +Perimeter of upper triangle -Perimeter of two small triangles at the bottom

Perimeter = 28 -(3+6+6.708) -(3+3+4.2426) +(3+9+9.486

Perimeter = 23.5354 mi

Therefore , The area of the figure is 45 sq.mi and the perimeter is 23.5354 mi.

Answer:

X=8

Step-by-step explanation:

If you divide 5 by 2 you get 2.5. To figure out X, all you have to do is divide 20 by 2.5 as well, which gets 8. Since they are similar, this can work.
