Answer:
B
Step-by-step explanation:
To factor the given function, find a term that is divisible by both terms. For this problem, the factor would be 2, since 2x^2 and -18 are both divisible by 2.
2(x^2 - 9)
You could further factor out x^2 - 9 because it is factorable by (x - 3) and (x + 3). Thus, it would be
2(x -3)(x+3)
Answer:
4400
Step-by-step explanation:
Use the LCM of two or more numbers Calculator to find the Least Common Multiple of numbers 80, 50, 110 i.e. 4400 smallest integer divisible by all numbers. Least common multiple (LCM) of 80, 50, 110 is 4400.
Hello,
x²/25+y²/9=1
