<h2><u>D.</u></h2><h3>It's incorrect, because 6 squared = 36, 8 squared = 64, add them together and you get 100. 12 squared does NOT equal 100, it equals 144.</h3>

<em>(To find the hypotenuse {longest side of the triangle}, you square the two short sides, add them together, and finally, divide it by the provided number, and see if the number matches the provided number's square.)</em>

<h3>Brainly if correct and Thanks!</h3>

Answer:

D) No, because 6²+8²≠12²

Step-by-step explanation:

In order for it to be a right triangle, the sum of the squares of the side lengths must be equal to the square of the hypotenuse.

In this case, 6^2+8^2=36+64=100. Since 100≠144, this means that option D is correct

Answer:

Step-by-step explanation:

(96 minutes)/(32 sculptures) = (96/32 minutes)/sculpture = (3 minutes)/sculpture

It takes 3 minutes to make one sculpture.

(160 balloons)/(32 sculptures) = (160/32 balloons)/sculpture = (5 balloons)/sculpture

It takes 5 balloons to make one sculpture.

(160 balloons)/(96 minutes) ≈ 1.7 balloons used per minute.

The radius of a semicircle is 3 feet. What is the semicircle's area?<br>Use 3.14 for Pi

valentinak56 [21]

Answer:

14.13 ft²

Step-by-step explanation:

The area of a semicircle is

$= \frac{\pi \: {r}^{2} }{2}$

We were given the radius of the semicircle to be: r=3 feet.

We were also asked to use π as 3.14.

We substitute into the formula to get:

$= \frac{3.14 \times {3}^{2} }{2}$

This is the same as:

$= \frac{3.14 \times 9}{2}$

Or

$= 3.14 \times 4.5$

$= 14 .13 {ft}^{2}$

The area of the semicircle is 14.13 ft²

1 Factor completely.

p2+7p+10 = (p + 5)(p + 2)

2 Factor completely.

x2+10x+16 = (x + 4)(x + 6)

3 Factor completely.

x2+7x−18 = (x + 9)(x - 2)

4 Factor completely.

x2−5x−24 = (x - 8)(x + 3)

5 Factor completely.

x2−3x−40 = (x - 8)(x + 5)
