<em>Answer:</em>
<em>r = -</em><em />
<em>Step-by-step explanation:</em>
<em>Rewrite the equation as </em><em> = m</em>
<em>Remove the radical on the left side of the equation by squaring both sides of the equation.</em>
<em>(</em><em> = m^2</em>
<em>Then, you simplify each of the equation. </em>
<em>Rewrite: (</em><em> as </em><em />
<em>Remove any parentheses if needed.</em>
<em>Solve for r. </em>
<em>Multiply each term by r and simplify."</em>
<em>Multiply both sides of the equation by 5.</em>
<em>6a+r= m^2r⋅(5)</em>
<em>Remove parentheses.</em>
<em>Move 5 to the left of (m
^2) r
</em>
<em>6a+r=5m^2)r</em>
<em>Subtract 5m^2)r from both sides of the equation.</em>
<em>6a+r-5m^2)r=0</em>
<em>Subtract 6a from both sides of the equation.</em>
<em>r-5m^2)r=-6a</em>
<em>Factor r out of r-5m^2)r </em>
<em>r(1-5m^2)=-6a</em>
Divide each term by 1-5m^2 and simplify.
r = -
There you go, hope this helps!
Answer:
The correct option is 4.
Step-by-step explanation:
It is given that figure ABCD is transformed to figure A′B′C′D′.
The vertices of ABCD are A(1,1), B(3,3), C(4,2) and D(4,1).
The vertices of A'B'C'D' are A'(1,-3), B'(3,-1), C'(4,-2) and D'(4,-3).
It is clear that the figure translate 4 units down and the rule of translation is
Translation is a rigid transformation, it means image and preimge are congruent.
Since ABCD is translate 4 units down to make A′B′C′D′, therefore
Congruent part of congruent figures are congruent.
Therefore the correct option is 4.

It is 28 i think been 3 year since i did this
70
because the little lines on the lines mean that the bottom two angles are the same
180-40=140
140/2=70
