n200080 [17]

<u><em>Answer: =204 *The answer should be have a positive sign.*</em></u>

Step-by-step explanation:

This question it's about PEMDAS. This lesson it's about order of operation. p-parenthesis, e-exponents, m-multiply, d-divide, a-add, and s-subtract. It must be go left to right.

do parenthesis first.

12(8+9)

9+8=17

multiply left to right.

12*17=204

=204

Hope this helps!

Thanks!

Have a great day!

The radius of a sphere is 6 inches. Find the length of a chord connecting two perpendicular radii. x = inches
Lilit [14]
<h3>Answer:</h3>

6√2 ≈ 8.485 inches

<h3>Step-by-step explanation:</h3>

The radii and the chord together make an isosceles right triangle with legs 6 inches long. The hypotenuse of such a triangle is √2 times the leg length. So, the chord will be 6√2 in long.

_____

<em>Comment on isosceles right triangle</em>

It is worth remembering that the hypotenuse of an isosceles right triangle is √2 times the leg length. This is easily found using the Pythagorean theorem:

... c² = a² + b²

... c² = 1² + 1² = 2 . . . . for legs of length 1

... c = √2 . . . . . . . . . . take the square root.

Scale this result as needed for any particular problem. Here, the scale factor is 6 inches.

The third side is described in relation to one of the
Ann [662]

<u>Complete Question: </u>

An isosceles triangle has two sides of equal length. The third side is 5 less than twice the length of one of the other sides. If the perimeter of the triangle is 23 cm, what is the length of the third side The third side is described in relation to one of the equal sides, so let x = the length of one of the equal sides. Which equation models the problem?

O x + x + (5 – 2 x) = 23

O x + x + (2 x – 5) = 23

O x + x + (2 x + 5) = 23

O X + (2 x - 5) + (2 x - 5) = 23

<u>Answer: </u>

The equation models the problem is x + x + (2 x – 5) = 23

<u>Step-by-step explanation:</u>

Given:

An isosceles triangle has two sides of equal length, so let x = the length of one of the equal sides .

The third side is 5 less than twice the length of one of the other sides. So, the third side is described as 2 x - 5.

The perimeter is the sum of the side lengths and given it as 23. Therefore, form the equation as below,

                Perimeter = x + x + (2 x-5)

Given perimeter of triangle = 23 cm. Hence,

                x + x + (2 x-5) = 23

The above equation models the given problem.
