For 9, the answer would be -4
And for 10, the answer should be 47°
Answer:
Step-by-step explanation:
take lcm of (2x-1)(x+2)
lcm=(2x-1)(x+2)
=2(x+2)-1(2x-1)/(2x-1)(x+2)
=(2x+4)-(2x-1)/(2x(x+2)-1(x+2)
=2x+4-2x+1/2x^2+4x-x+2
=4+1/2x^2+3x+3
=5/2x^2+3x+3
Answer:
Step-by-step explanation:
1) Separate terms with roots from terms without roots.
![x^2+4=\sqrt[\frac{1}{2} ]{4+1}](https://tex.z-dn.net/?f=x%5E2%2B4%3D%5Csqrt%5B%5Cfrac%7B1%7D%7B2%7D%20%5D%7B4%2B1%7D)
2) Simplify 4 + 1 to 5.
![x^2+4=\sqrt[\frac{1}{2} ]{5}](https://tex.z-dn.net/?f=x%5E2%2B4%3D%5Csqrt%5B%5Cfrac%7B1%7D%7B2%7D%20%5D%7B5%7D)
3) Invert and multiply.
4) Simplify 
to 25.
5) Subtract 4 from both sides.
6) Simplify 25 - 1 to 24.
7) Take the square root of both sides.
Knowing she makes $9 for each 1 hour, you know that if you'd need to find how much she made after 4 hours, you would do 9(4), giving you the answer of $36.
With this knowledge, you can replace the 4 with h.
9(h)=P
The reason why it's such a simple equation is because it's per hour and nothing else is being increased, decreased, or changed.
Hope this helps!
