Given data:
The first given length is AC=53.
The second given length is AB= 45.
The expression for the Pythagoras theorem is,
Here, consider only positive sign of BC length as side cannot negative.
Thus, the BC length is 28.
Answer:
If the rows of this cone is square shaped:
4*4=16
3*3=9
2*2=4
1
16+9+4+1=30
the formula:
Step-by-step explanation:
Answer:a valid solution is (1,3)
Explanation:First, let' simplify the given equation:
14mn = 55 - 7m - 2n
14mn + 2n = 55 - 7m - 2n + 2n
n (14m + 2) = 55 - 7m
n =
Now, we have only one equation in two unknowns. Therefore, the only way to solve this is by assuming one of the variables and solving for the other taking into consideration that both should be positive integers.
1- Assume m = 2:
n =
.....> n is not a positive integer .........> This assumption is rejected
2- Assume m = 1:
n =
.......> both m and n are positive integers ........> This assumption is accepted ...........> Therefore, the solution would be (1,3)
Hope this helps :)
