Sorry. I wish i could show my work, but I can upload my picture work. I will post that here when my computer is working again.
Answer:
Two triangles are similar if they have: all their angles equal; corresponding sides are in the same ratio; But we don't need to know all three sides and all three angles ...two or three out of the six is usually enough. There are three ways to find if two triangles are similar: AA, SAS and SSS: AA

Answer:
y31
Step-by-step explanation:
aM×aN=aM+N
so. y3+8+1+7+12=y31

Understand factoring.
Write a space for the answer in FOIL form.<span>
Don't write + or - between the blank terms yet, since we don't know which it will be.
</span>
<span>Fill out the First terms.
</span>
<span>Use factoring to guess at the Last terms.
</span>
<span>Test which possibilities work with Outside and Inside multiplication.
</span>
<span>Use simple factoring to make more complicated problems easier.
</span>
<span>Look for trickier factors.
</span>
<span>Solve problems with a number in front of the x^2.
</span>
<span>Use substitution for higher-degree trinomials.
</span>
Check for prime numbers.
Check to see if the trinomial is a perfect square.
<span>Check whether no solution exists.
</span>
If both binomials have the same variables to the same powers, then it is true. In general, multiplying binomials gives four terms, one corresponding to each letter of the FOIL acronym. So, you only get a trinomial when the O and I terms combine.
