Answer:

x = 2 1/3

y = 14 / (2 1/3) = 14 / (7/3) = 14*3/7 = 42/7 = 6

y = 6

x = 4 1/5

y = 14 / (4 1/5) = 14 / (21/5) = 14*5/21 = 70/21 = 3 7/21 = 3 1/3

y = 3 1/3

x = 7/6

y = 14 / (7/6) = 14*6 / 7 = 12

y = 12

Step-by-step explanation:

y=6, y=3 1/2, and y=12

The width of a rectangular sandbox is two less than twice the length. The perimeter of the sandbox is 26 feet. Identify the length and width of the sandbox. (Remember 2l+2w=Perimeter)

Answers

[tex]l = 5 \\ w = 8[/tex]

5 + 5 + 8 + 8 = 26 and since 5 x 2 - 2 = 8 it matches with the problem

let’s say the length is x. That would mean that the width is 2x-2.

using this we would have this equation:
2x+ 2(2x-2) = 26

distribute

2x+ 4x-4= 26

add like terms

6x-4=30

add 4 to both sides

6x=30

divide

x= 5

since x is our length, the length is 5

now for the width, use the 2x-2 equation and plug in x. you should get 8

l= 5
w=8

i hope this helps!!

HELP!! For the following right triangle, find the side length x. Round your answer to the nearest hundredth. 17 a X 12

Answers

Answer:For this problem, you will need to use the pythagorean theorem which is

So a and b are usually the sides that are NOT the hypotenuse, or in this case the long side that is not at a 90 degree angle.

You will start by plugging 12 into with (a) or (b) but not both. And then you will plug 17 in for (c). Make sure you square these values to solve the equation. Once you do that, it is basic algebra from there to solve for the missing variable. If you want to check to see if your answer is correct, then plug all the side numbers back into the equation. Also your answer should be between 12 and 17, or possibly one of those numbers.

Step-by-step explanation: I hope this helps!! God Bless you. Have a great day!!!!

The Pythagorean theorem is sometimes known as Pythagoras' theorem. The value of x can be written as 12.0416 units.

What is Pythagoras' theorem?

The Pythagorean theorem, sometimes known as Pythagoras' theorem, is a basic relationship between the three sides of a right triangle in Euclidean geometry. The size of the square whose side is the hypotenuse is equal to the sum of the areas of the squares on the other two sides, according to this rule.

Given that the length of a perpendicular side is x, while the length of the base of the triangle is 12. Also, the length of the hypotenuse is 17 units. Therefore, we can write,

Perpendicular² + Base² = Hypotenuse²

x² + 12² = 17²

x² + 144 = 289

x² = 289 - 144

x² = 145

x = √145

x = 12.0416

Hence, the value of x can be written as 12.0416 units.

A square rug has an inner square in the center. The side length of the inner square is x inches and the width of the outer region is 2 in. What is the area of the outer part of the rug?

Answers

Answer:

so Area of Outer part = 8x + 16 square inches

Step-by-step explanation:

2 squares.

inner square dimension is x inches by x inches.

width of outer region= 2inches.

We want the area of the border around the inner square.

Area of border = B = Area of Large - Area of Inner

B = (x+4)^2 - x^2

B = x^2 + 8x + 16 - x^2

B = 8x + 16 square inches

so Area of Outer part = 8x + 16 square inches
