To find the hypotenuse of a right triangle you can use the Pythagorean theorem. (a² + b² = c²) Using the measurements provided we can solve like this.


Both a² & b² = 7²


7 x 7 = 49


49 + 49 = 98


Now we need to find the square root of 98 (c²) to get our answer.


9.9 x 9.9 = 98.01 or about 98


The measurements for the tirangle are 7 units, 7 units, and 9.9 units.


Hope this helps!

<u>Answer:</u>

9.89 units

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

We are a given a right angles triangle which has side lengths 7 units each (of the perpendicular and the base) and we are supposed to find the length of the hypotenuse.

We can find the length of the hypotenuse by using the Pythagoras Theorem:

a^2= b^2+c^2

where a is the hypotenuse and b and c are the perpendicular and base.

a^2=7^2+7^2\\\\a^2=49+49\\\\a^2=98\\\\\sqrt{a^2} =\sqrt{98} \\\\a=9.89

Therefore, the length of the hypotenuse id 9.89 units.

Two balls A and B rotate along a circular track. Ball A makes 4 full rotations in 120 seconds. Ball B makes 3 full rotation in 6
lara [203]
Find the rate in which both balls make one full rotation around the track.

Ball A:

120 / 4 = 30

It takes 30 seconds for Ball A to make a full rotation.

Ball B:

60 / 3 = 20

It takes 20 seconds for Ball B to make a full rotation.

Find the least common multiple of 20 and 30 to find the time at which they'll meet.

Multiples of 20: {20,40,60}
Multiples of 30: {30,60}

60 is the least common multiple of both 20 and 30.

The balls will meet again at 60 seconds.

Answer:

(x^2 + x -1) x (x^2+3x-3)

Step-by-step explanation:

-6x-5+x^4+4x^3-x^2+8

-6x+3+x^4+4x^3-x^2

-6x+3+x^4+x^3+3x^3-x^2

-3x-3x+3+x^2 x(x^2+x-1)+3x^3 +3x^2-3x^2

3x *(x^2+x+x-2)-3(x^2+x-1)+x^2 *(x^2+x-1)

= (x^2+x-1) x (x^2+3x-3)
