kimi is playing hide-and-seek with Tommy and Manuel. Tommy is hiding 12 feet south of Kimi, and Manuel is hiding due east of Tom

ad-work [718]

Answer:

Tommy and Manuel are 16 ft apart

Step-by-step explanation:

The locations of all three players are shown in the image below

They form a right triangle where the hypotenuse is 20 ft, and one of the legs is 12 ft. We must find the other leg.

We must use Pythagoras's theorem. Being a and b the legs of a right triangle and c its hypotenuse, then

$c^2=a^2+b^2$

Knowing c and one of the legs, say b:

$a^2=c^2-b^2$

Using the values c=20, b=12 we find

$a^2=20^2-12^2=400-144=256$

$a=\sqrt{256}=16$

So, Tommy and Manuel are 16 ft apart

One of Marianna's homework problems was to solve the equation below.

Strike441 [17]

Answer:

<h2>Marianna is incorrect because x2</h2><h2>2x13 can be factored into two binomials</h2>

Step-by-step explanation:

ax^2+bx+c = 0

x=−1+√14 or x=−1−√14

discriminant=56

completing square x=−1+√14 or x=−1−√14

Now, we can solve each term for

x=-2 she is incorrect

x(x+2)=0

Now, we can solve each term for

x=0

- no other work needed,

and

x+2=0

x+2-2=0-2

x+0=-2
