Take the root of both sides, and then solve.
c = sqrt a^2 + b^2, - sqrt a^2 + b^2.
c = sqrt a^2 + b^2, - sqrt a^2 + b^2.
Using the PSN method:
P = -9
S = 8
So N = 9,-1
Using 9 and -1 in the original equation gives:
P = -9
S = 8
So N = 9,-1
Using 9 and -1 in the original equation gives:
Answer:
Total width of tables combined = 16 feet and 4 inches
Step-by-step explanation:
Given:
Width of tables
1) 6 feet 3 inches
2) 3 feet 7 inches
3) 6 feet 6 inches
The tables are combined. We need to find the total width.
Total width of the tables combined = Sum of the widths of the tables
⇒
Adding feet and inches together.
⇒
⇒
[∵ , we can split
⇒
⇒
⇒
Total width of tables combined = 16 feet and 4 inches
