In any triangle, a side is longer than the difference between the other two. A side is also less the the sum of the other two. If these two rules are not obeyed then a triangle cannot be formed by those sides.
a = 7 cm. b = 3 cm.
Then c > 7-3 = 4 cm and also, c < 7+3 = 10 cm.
4 cm < the third side < 10 cm
Answer:
15-9 will be greater
Step-by-step explanation:
Caroline wants to compare the expressions 15-9 and 9 (-15)
For us to know the result that is greater, we will have to check if the first value is less than or greater than the other. For example
If for a-b
a-b is greater if a>b
a-b is lesser if a<b
Given 15 - 9
Since 15 > 9, this means that 15-9 will be greater compare to 9-15
Answer:
The First one
Step-by-step explanation:
Just divide r/s and substitute x by 6.
Answer:
17s+20t
Step-by-step explanation:
Answer: (7,5) X=7 and Y=5
Explanation:
Add the two equations together to eliminate y from the system.
x-y=2 + x+y=12
= 2x = 14
Divide both sides by 2
x=7
Substitute the value found for x into one of the original equations to solve for y
(7)-y=2
Move all terms to one side to make it easier
-y=2-7
Subtract
y=5
