58 yards

P=2l x 2w

264=2(74) x 2w

264=148 x 2w

264-148=116

116/2 = 58

P=2l x 2w

264=2(74) x 2w

264=148 x 2w

264-148=116

116/2 = 58

For the center of this circle the right choice will be choice B. (-21,-19)

and its radius sqrt849 = 849^(1/2) so choice B. is right for this too

hope this will help you

When a square (or any rectangle) is inscribed in a circle, the diagonal

of the square (or rectangle) is a diameter of the circle.

Diagonal of this square = diameter = 2 x radius = 4√2 inches.

But the diagonal of a square is the hypotenuse of the right triangle that's

formed by cutting the square in half corner-to-corner.

So (diagonal)² = (side)² + (side)²

2 (side)² = (diameter)²

2 (side)² = (4√2)²

2 (side)² = 16 x 2 = 32

(side)² = 16

side =**4 inches**

Let x be the third side. The two cases that allow us to determine the length of the third side are: (1) let x be the hypotenuse and (2) let 8 be the hypotenuse and solve for x. Through the Pythagorean theorem,

Case 1. x² = 8² + 5² ; x = 9.4

Case 2. 8² = x² + 5² ; x = 6.2

Thus, the difference is approximately 3.2.

QUESTION POSTED AT 22/01/2020 - 01:43 AM

The area (A) of the triangle is the product of its length (l) and width (w). A = l x w. Since the width is 2 m shorter than the length, it may be expressed as w = l -2. The equation for area becomes,

A = l x (l - 2)

Substituting the known area and rearranging the equation gives,

l(l - 2) = 168.

A = l x (l - 2)

Substituting the known area and rearranging the equation gives,

l(l - 2) = 168.

QUESTION POSTED AT 22/01/2020 - 01:33 AM

Let x be the length of the playground. With this representation, the width may be expressed as x + 5. The area of a rectangular figure is the product of its length and width.

A = L x W

A = (x)(x+5) = 234 yd²

Solving for the value of x in the equation gives an answer of x = 13 and x = -18. The second value of x is not applicable to the problem since a negative number cannot be a value for length. Below is the calculation of the dimensions.

Length = x = 13 yards

Width = x + 5 = 18 yards

Thus, the length and width of the playground are 13 and 18 yards, respectively.

The length (L), width (W), and the diagonal (D) of the television screen make a right triangle with the legs L and W and hypotenuse D. Thus, their measurements are related through Pythagorean Theorem.

L² + W² = D²

Substituting the known values from the given,

(15 in)² + W² = (25 in)²

Solving for W in the equation gives, W = 20 in and W = -20. The second value is an extraneous root. Thus, the width of the television screen is 20 inches.

Each side of the square needs to be enlarged by x inches to obtain the new area which is 81. The area of the square is calculated by squaring the measure of its side.

A = (x + 4)²

From the given value of area,

(x + 4)² = 81

x ² + 8x + 16 = 81

Further simplification leads to the answer,

x² + 8x - 65 = 0

A = (x + 4)²

From the given value of area,

(x + 4)² = 81

x ² + 8x + 16 = 81

Further simplification leads to the answer,

x² + 8x - 65 = 0
