Answer:
the answer is d. 4x²+x-6
Step-by-step explanation:
In order to combine the fractions, they need to have the same denominator.
So, multiply each of their numerators by the denominator they need to be equivalent.
This would look like this:
3x/x+3 --> 3x(x)/x(x+3) ---simplify this as--> 3x²/x(x+3)
x-2/x --> (x-2)(x+3)/x(x+3) ---simplify this as --> x²+x - 6/x(x+3)
3x 3x(x) x-2 (x-2)(x+3)
----- ---> ----- and -------- ---> ---------
x+3 x(x+3) x x(x+3)
now that both fractions have the same denominator, we can add their numerators.
3x² + x²+x-6 = 4x²+x -6
This should now look like this:
4x²+x -6
-------------
x(x+3)
50 = x^2
To isolate x you need to do the opposite of an exponent, which would be square root.
![\sqrt{50} = x Next solve what the square root of 50 is[tex]5\sqrt{2}](https://tex.z-dn.net/?f=%5Csqrt%7B50%7D%20%3D%20x%20%3C%2Fp%3E%3Cp%3ENext%20solve%20what%20the%20square%20root%20of%2050%20is%3C%2Fp%3E%3Cp%3E%5Btex%5D5%5Csqrt%7B2%7D)
= x
That is the exact form, in other words your answer, if teacher is looking for a decimal, it would be
7.07 = x
Table B of course they follow by the order instead of table A
Answer:
See below
Step-by-step explanation:
What we can do is try it out.
20*0.6=12
since 0.6 is left
now we increase 12 by 40, or multiply it by 1.4
12*1.4= 16.8
See what is happening here is that at first when we are decreasing it by 40 percent, we are taking 40 percent of 20. However, when we increase that amount by 40 percent, we are now increasing 40 percent of 20 by 40 percent, or increasing 16 by 40 percent. Therefore, we will not get the original amount.
