This would be so easy for you to solve, in about 3 minutes with a calculator.
A fraction means division ... (the top number) divided by (the bottom number).
Take the fraction part of each choice, do the division for each one,
and see which one gives you 0.4545... repeating.
A). 227/500 = 0.454 That's not 0.45 repeating.
B). 9/20 = 0.45 That's not 0.45 repeating.
C). 5/11 = 0.4545... THAT's 0.4545... repeating !
D). 9/2 = 4.5 That's not 0.45 repeating.
Answer:
4x^2+8x-5
Step-by-step explanation:
You work backwards to get (2x-1) which gets you the root 1/2 and (2x+5) which gets you the root -5/2 after this you foil what you have so (2x-1) times (2x+5). You do 2x times 2x which gives you 4x^2 2x times 5 which gives you 10x -1 times 2x which gives -2x and lastly -1 times 5 which gives you -5 now you combine like terms and get your final answer of 4x^2+8x-5
Answer:
is it's right answer is 572
4a + 2b = 10
you are solving for b
isolate the b
subtract 4a from both sides
4a (-4a) + 2b = 10 (-4a)
2b = 10 - 4a
divide 2 from both sides to isolate the b
2b(/2) = (10 - 4a)/2
b = (10 - 4a)/2
b = 5 - 2a
C) b = -2a + 5 is your answer
hope this helps
