Answer:
2/5√2
Step-by-step explanation:
2/√ 25 * 2
further:
ans (1/5)(√2)
X2 = x2 + 2x + 9 Now subtract x2 from both sides and you have
x2- x2 = x2 - x2 + 2x + 9 or 0 = 2x + 9 now subtract 9 from both sides so you can solve for x.
0 -9 = 2x -9...and you have -9 = 2x
Now solve for x by dividing both sides by 2 and you arrive at x = -4.5
Just multiply .45 to 220, giving you an answer of 99. If you don't understand this concept, feel free to ask me to explain it further in the comments.
