Given:
Susie's dog is 2 feet tall. When she measures her dog in inches he was 24 inches.
To find:
Why is there an increase in inches.
Solution:
It is given that Susie's dog is 2 feet tall.
We know that,
1 feet = 12 inches
Using this conversion, we get
2 feet = 2×12 inches
2 feet = 24 inches
So, the measures 2 feet and 24 inches are equal.
Therefore, if Susie's dog is 2 feet tall then he is 24 inches tall because both of these measure are equal.
WHat else is to the question?!?
Noting that square A is a square, this is what we have:
A = B
A^2 = B x (B + 4) + 20
I can try subbing in A to B
since A = B:
A^2 = A x (A + 4) + 20
20 = A^2 - (A x (A + 4))
20 = A^2 - (A^2 + 4A)
20 = 4A
A = 5
By the way, A is width of square A and B is the width of rectangle B in my solution,
5 is the number
3n - 2 = n + 10 add 2 to both sides
3n = n + 10 subtract n from both sides
2n = 10 divide both sides by 2
n = 5
