This is known as Einstein's proof, not because he was the first to come up with it, but because he came up with it as a 15 year old boy.
Here the problem is justification step 2. The written equation
BC ÷ DC = BC ÷ AC
is incorrect, and wouldn't get us our statement 2, which is correct.
For similar triangles we have to carefully pair the corresponding parts to get our ratios right:
ABC ~ BDC means AB:BD = BC:DC = AC:BC so BC/DC=AC/BC.
Justification 2 has the final division upside down.
The dimensions are factors of the expression
... you multiply them together to get the area
the factors are ... (x - 7) & (x + 2)
Hello there! :)
<u><em>Answer:
</em></u>
<u><em>*The answer must have a fraction.*</em></u>
Step-by-step explanation:
Lesson: Zero and Negative Exponents.
Distributive property: a(b+c)=ab+ac
First, you apply exponent rule.
