yulyashka [42]
Hi! A and B are definitely not the right answers, because that’s basically rotating it forward even more. Rotating a polygon in Quadrant II 370 degrees clockwise is like rotating it 99 degrees counterclockwise, because the next 90 degrees you were to rotate it, it would be in it’s original position. The answer is C.

2(x+3)=2x+6 how many solutions dose it have
LekaFEV [45]

<em>Answer:</em>

<em>The right side of the equation is only a different way of writing the left side, so any value of x will solve this equation. </em>

<em> </em>

<em>The equation   − 2 (  x  +  3  )  =  − 2 x  −  6  does not have any specific solutions for the simple reason that the left and rigth sides are two representations of the same equation. </em>

<em> We have  − 2 (  x  +  3  )  means that each term inside the parenthesis should be multiplied with  − 2 , i.e.</em>

<em> − 2 (  x  +  3 )  =  − 2  ⋅  x  −  2  ⋅  (  +  3 )  =  − 2 x  −  6 </em>

<em> </em>

<em>Which is exactly what the right side says. </em>

<em> </em>

<em>Any value of x will, therefore, fulfill this equation.</em>

Which of the following equations can be used to find the length of EF in the
Vinil7 [7]

The equation which can be used to find the length of EF is option A which is  EF=\sqrt{24^{2} -12^{2} }.

Given the length of base of right angled triangle is 12 and the hypotenuse be 24.

We are to find the length of EF and tell which equation can be used to find the length of EF.

We know that pythagoras theorem applies in a right angled triangle.

Pythagoras theorem says that in a right angled triangle the square of the hypotenuse is equal to the sum of square of base and perpendicular.

H^{2} =B^{2} +P^{2}

In this triangle we are only given base and hypotenuse and we have to find EF which is perpendicular.

(DE)^{2} =(EF)^{2} +(DF)^{2}

EF=\sqrt{DE^{2}-DF^{2}  }

=\sqrt{(24)^{2} -(12)^{2} }--1

=\sqrt{576-144}

=\sqrt{432}

Hence the equation which can be used to find the length of Ef is option A which is  EF=\sqrt{24^{2} -12^{2} }.

Question is incomplete as it should include the figure also.
