Answer:
(x - 10)(x + 10)
Step-by-step explanation:
x² - 100 ← is a difference of squares and factors in general as
a² - b² = (a - b)(a + b)
Hence
x² - 100
= x² - 10² = (x - 10)(x + 10)
The shortest distance between 2 concentric circles is the difference of their radii. Thus the answer is 8-2=6
B 6x - 3
help theres a character limit
12=-12+x
or are you looking for something like you provided us in your question
"<span>(example 3x+4y=19 )"</span>
