Answer:
There are no solutions
<u>Steps : </u>
First we expand it
Then we add 3 to both sides
Then we simplify
Then we subtract 6b from both sides
Simplify
<u>No solutions !</u>
Answer: the other two sides are 5 feet and 12 feet
Step-by-step explanation:
Length of one side be x , that means the other side is x + 7
by Pythagoras theorem:
+ =
expanding , we have:
+ + 14x + 49 = 169
+ 14x + 49 - 169 = 0
+ 14x - 120 = 0
divide through by 2 , we have
+ 7x - 60 = 0
By factorizing , we have
(x - 5)(x+12) = 0
Therefore:
x = 5 or x = -12
Since , the side can not be negative , so
x = 5
That means the other side will be 5+ 7 = 12
The answer is x = 3 because is we substitute 3 for x, we get 6 on both sides. 3(3) - 3 = 2(3) (=) 9 - 3 = 6 (=) 6 = 6.
