Answer: Choice D) 11
----------------------------
Work Shown:
cos(angle) = adjacent/hypotenuse
cos(35) = 9/x
x*cos(35) = 9
x = 9/cos(35)
x = 10.9869712988531 ... make sure your calculator is in degree mode
x = 11 ... rounding to the nearest tenth
Answer:
The answer is (x - 9)(x - 2), or x2 - 11 + 18.
Step-by-step explanation:
Well, think about it. What two numbers add to -11 and multiply to get 18? -9 and -2 add to get -11 and multiply to get 18.
Answer:
9725
Step-by-step explanation:
5+6(4)*45*9
5+6(4)*405
5+24*405
9725
I hope you mean 1/5 when you say 1 5. If that's what you mean, then both, Joshua and Melanie, are correct because, both of their equations are the same.
Joshua's - <span>8 ÷ 1/5 = 40 (Since we can divide a number by fraction, we use this rule: keep, change flip. When we use that Joshua's equation turns into 8 * 5/1 = 8*5 = 40, same as Melanie's.)</span>
The answer is b -9 < x < 12
