Answer:
The answer is the option C
![1+\frac{2}{5}x](https://tex.z-dn.net/?f=1%2B%5Cfrac%7B2%7D%7B5%7Dx)
Step-by-step explanation:
we have
![2+\frac{3}{5}x-1-\frac{1}{5}x](https://tex.z-dn.net/?f=2%2B%5Cfrac%7B3%7D%7B5%7Dx-1-%5Cfrac%7B1%7D%7B5%7Dx)
Group terms
![2+\frac{3}{5}x-1-\frac{1}{5}x=(\frac{3}{5}x-\frac{1}{5}x)+(2-1)](https://tex.z-dn.net/?f=2%2B%5Cfrac%7B3%7D%7B5%7Dx-1-%5Cfrac%7B1%7D%7B5%7Dx%3D%28%5Cfrac%7B3%7D%7B5%7Dx-%5Cfrac%7B1%7D%7B5%7Dx%29%2B%282-1%29)
![=(\frac{2}{5}x)+(1)](https://tex.z-dn.net/?f=%3D%28%5Cfrac%7B2%7D%7B5%7Dx%29%2B%281%29)
![=1+\frac{2}{5}x](https://tex.z-dn.net/?f=%3D1%2B%5Cfrac%7B2%7D%7B5%7Dx)
X^2 +mx +m = (x+2 )^2
since (x+2)^2 = x^2 +2(2x) + 2^2
= x^2 + 4x + 4
therefore the answer is m= 4

Answer:
x = 23/16
Step-by-step explanation:
x + 1/16 = 3/2
Get a common denominator
x + 1/16 = 3/2 *8/8
x + 1/16 = 24/16
Subtract 1/16 from each side
x+1/16 -1/16 = 24/16 -1/16
x = 23/16
