These are "composite" functions.
g(x+a) means insert (x+a) into g(x) to replace every x:
g(x+a) - g(x) = -5(x+a)^2 +4(x+a) +5x^2 - 4x
= -5(x^2 + 2ax + a^2) +4x +4a + 5x^2 - 4x
Now just Multiply and sum up the answer.
Answer:
the word similar means when to things are alike, it compares to congruent because congruent means thing are in harmony.
Things I would say are similar is a blanket and a sheet because they both provide coverage and warmth.
If I said things are similar it is because they are alike in meanings, or appearence.
I would use similar over congruent because congruent isn't a word you hear often. When you do hear it is mostly used to talk about angles and lines.
Your answer should be, 3x= 22y to the tenth power...
