Answer:
There are no values of x that make the equation true
The system has no solution
Step-by-step explanation:
we have
Solve for x
Subtract x both sides
-----> is not true
therefore
Is a inconsistent system
There are no values of x that make the equation true
The system has no solution
<h3>Answer:</h3>
D. If x2 = 9, then x = 3.
<h3>Explanation:</h3>
The converse reverses the order of phrases in "if p then q" so it becomes "if q then p". Here, that makes the converse ...
... If x^2 = 9, then x = 3.
The converse is not true (x may be -3), so we're finished with the problem. The appropriate choice is the one indicated above.
The first thing we are going to do is distribute:
=<span>4x+(6)(3x)+(6)(−2)
</span>=<span><span><span><span>4x</span>+<span>18x</span></span>+</span>−<span>12
</span></span>Second thing we are going to do is C<span>ombine Like Terms:
</span>=<span><span>4x+18x</span>+<span>−<span>12
=</span></span></span><span>(<span><span>4x</span>+<span>18x</span></span>)</span>+<span>(<span>−12</span><span>)
</span></span>And your final answer is:
<span>22x</span>+<span>−<span>12</span></span>
I hope this helps you! :)
x= 6√5
1) Considering the right triangle metric relations and examining the picture, in which we're looking for the altitude of the triangle. Let's pick the one for the height of the right triangle and the projections of the hypotenuse: 20,9
h²= m.n <em>In this triangle we can rewrite it as</em>
x²=20*9
√x²=√180
x=6√5, and -6√5 <em>The negative value does not fit into that</em>
So, x= 6√5
