Answer:
The length of CD is 8 units
Step-by-step explanation:
<u><em>The complete question in the attached figure</em></u>
we know that
According to the Right Triangle Altitude Theorem,
substitute the given values
solve the quadratic equation by graphing
The solution is x=8 or x=-6
see the attached figure N 2
Discard the negative length.
therefore
The length of CD is 8 units
Answer:
5(x+2)=6x+3x−14
Step 1: Simplify both sides of the equation.
5(x+2)=6x+3x−14
(5)(x)+(5)(2)=6x+3x+−14(Distribute)
5x+10=6x+3x+−14
5x+10=(6x+3x)+(−14)(Combine Like Terms)
5x+10=9x+−14
5x+10=9x−14
Step 2: Subtract 9x from both sides.
5x+10−9x=9x−14−9x
−4x+10=−14
Step 3: Subtract 10 from both sides.
−4x+10−10=−14−10
−4x=−24
Step 4: Divide both sides by -4.
−4x
−4
=
−24
−4
x=6
Answer:
x=6
-7 is the answer to this question
He did not walk 1/2 a mile. Because it's a round-trip, it's technically 2 miles long. so, in the end, he did not walk 1/4 of the trip. Hope this helps :)
