Answer:

The answer is NO

Step-by-step explanation:

Firstly, any <em>right triangle</em> has to obey the Pythagorean Theorem Formula.

This theorem says:

If a, b are two sides of the triangle and c is the hypotenuse, the formule is:

a^2+b^2=c^2

There are few combinations of whole numbers that satisfy the equation. They are called "Pythagorean Triples". I have attached an image that it shows these combinations. You can choose whatever combination and its multiples satisfy the equation as well.

Finally, if you see the image, there are not combination where the hypotenuse is 23.

No, u cant

a^2 + b^2 = c^2.....pythagorean theorem used on only right triangles...where a and b are the legs and c is the hypotenuse

a^2 + b^2 = 23^2
a^2 + b^2 = 529...so u would have to find 2 square numbers that add up to 529. There aren't any.

Nookie1986 [14]

Hello!

1. 8y = 48 => y = 48 : 8 => y = 6

2. q - 12 = 1 => q = 1 + 12 => q = 13

3. 18 = a/2 => a = 18 × 2 => a = 36

4. r/3 = 7 => r = 3 × 7 => r = 21

5. 11 = m - 4 => m = 11 + 4 => m = 15

Good luck! :)

The distance from one corner of a rectangular garden to the other is 13 ft. The length of the garden is 7 ft longer than the wid
coldgirl [10]

Answer:

  • dimensions: 12 ft by 5 ft
  • area: 60 ft²

Step-by-step explanation:

Let x represent the shorter dimension in feet. Then the longer one is x+7 and the Pythagorean theorem tells us the relation of these to the diagonal is ...

  x² + (x+7)² = 13²

  2x² +14x + 49 = 169 . . . . eliminate parentheses

  x² +7x -60 = 0 . . . . . subtract 169 and divide by 2

  (x +12)(x -5) = 0 . . . . factor the equation

  x = -12 or +5 . . . . . . . only the positive value of x is useful here.

The short dimension is 5 ft, so the long dimension is 12 ft. The area is their product, 60 ft².

_____

<em>Comment on finding the area</em>

The quadratic equation above can be rearranged and factored as ...

  x(x +7) = 60

Since the dimensions of the garden are x and (x+7), this product is the garden's area. This equation tells us the area is 60. We don't actually have to find the dimensions.

The painting shown at the right has an area of 220. What is the value of x?
tangare [24]

Answer:

9.76

Step-by-step explanation:

area of a rectangle = length * breadth

length = (2x + 3)

breadth = x

given area is 220 sq. inches.

thus,

220 = x * (2x+3)

220 = 2x² +3x

2x² + 3x -220 = 0

x = (-b + √ ( b²-4ac) ) ÷ 2a

x = ( -3 + √ ( 3² - 4*2*220) ) ÷ 2*2

x =9.76
