<h2><u>Solution (1)</u> :</h2>
Given, to find A we have to :
- square m
- Add y to m²
- Subtract 7 from m² + y
From the question, the following equation can be formed :
![=\tt A = {m}^{2} + y - 7](https://tex.z-dn.net/?f=%20%3D%5Ctt%20%20A%20%3D%20%7Bm%7D%5E%7B2%7D%20%20%20%2B%20y%20-%207)
Therefore, the formula for finding A = m² + y - 7
<h2><u>Solution (2)</u> :</h2>
The value of A we can derive from the formula is :
![=\tt A = {m}^{2} + y - 7](https://tex.z-dn.net/?f=%20%3D%5Ctt%20A%20%3D%20%20%7Bm%7D%5E%7B2%7D%20%20%2B%20y%20-%207)
Value of m = 3 (given)
Which means :
![=\tt A = {3}^{2} + y - 7](https://tex.z-dn.net/?f=%20%3D%5Ctt%20A%20%3D%20%20%20%7B3%7D%5E%7B2%7D%20%20%2B%20y%20%20-%207)
![=\tt \: A = 9 + y - 7](https://tex.z-dn.net/?f=%20%3D%5Ctt%20%5C%3A%20A%20%3D%209%20%2B%20y%20-%207)
![=\tt A = 9 - 7 + y](https://tex.z-dn.net/?f=%20%3D%5Ctt%20A%20%3D%209%20-%207%20%2B%20y)
![\color{plum} =\tt A = 2 + y](https://tex.z-dn.net/?f=%5Ccolor%7Bplum%7D%20%3D%5Ctt%20A%20%3D%202%20%2B%20y)
Thus, the value of A = 2+y
Therefore, the value of A = <u>2+y</u>

Step-by-step explanation:
Given
Rob is twice Joshua's age
Nick is 5 years older than Joshua.
sum of all their ages is 45.
Find the age of nick.
To proof
As given
Rob is twice Joshua's age
let Joshua's age = x
than Rob age = 2x
Nick is 5 years older than Joshua.
Nick age = 5 + x
sum of all their ages is 45
than the equation becomes
Joshua's age + Rob age + Nick age = 45
put the value
x + 2x + 5 + x = 45
4x = 40
x = 10
Joshua's age = 10 year
than Rob age = 20 year
Nick age = 5 + 10
= 15year
Hence proved
Considering the relation built the presence of point M on line LN, the numerical length of LN is of 9 units.
<h3>What is the relation from the presence of point M on the line LN?</h3>
Point M splits line LN into two parts, LM and MN, hence the total length is given by:
LN = LM + MN.
From the given data, we have that:
Hence we first solve for x.
LN = LM + MN.
2x - 5 = 3 + x - 1
x = 7.
Hence the total length is:
LN = 2x - 5 = 2 x 7 - 5 = 14 - 5 = 9 units.
