</u>
We are given the following relations:
![a=\sqrt{7}+\sqrt{c}\qquad \qquad[1]](https://tex.z-dn.net/?f=a%3D%5Csqrt%7B7%7D%2B%5Csqrt%7Bc%7D%5Cqquad%20%5Cqquad%5B1%5D)
![b=\sqrt{63}+\sqrt{d}\qquad \qquad[2]](https://tex.z-dn.net/?f=b%3D%5Csqrt%7B63%7D%2B%5Csqrt%7Bd%7D%5Cqquad%20%5Cqquad%5B2%5D)
![\displaystyle \frac{c}{d}=\frac{1}{9} \qquad \qquad [3]](https://tex.z-dn.net/?f=%5Cdisplaystyle%20%5Cfrac%7Bc%7D%7Bd%7D%3D%5Cfrac%7B1%7D%7B9%7D%20%5Cqquad%20%5Cqquad%20%5B3%5D)
From [3]:

Replacing into [2]:

We can express 63=9*7:

Taking the square root of 9:

Find the ration a:b:

Simplifying:

Answer:
midpoint formula:
x1+x2/2 y1+y2/2
-4 + (-2)/2 which then simplifies to -6/2 and then to -3
2 + 2 /2 which then simplifies to 2
x= -3
y= 2
so (-3,2) is the coordinate point of the midpoint of this segment
Answer:
the number of vegetables did farmer bring in the market is 1764 vegetables
Step-by-step explanation:
The computation of the number of vegetables did farmer bring in the market is shown below:
= 18 bags × 42 kgs + 28 bags × 36 kgs
