The correct answer is exactly one triangle
Answer:
4
Step-by-step explanation:
The radius of the circle times 2 to make it the diameter, because the diameter of the circle is the same as the side length.
Answer:
2a+4b-c
Step-by-step explanation:
Combining like terms: 3b+b=4b
2a stays the same
-c stays the same
Since a and c does not match together they stay the same and not combine since they are not like terms.
A + b + c = 12
c = (a + b) - 2.....c - a - b = -2
3a + 1 = 2c
add the first 2 equations
a + b + c = 12
-a - b + c = -2
------------------add
2c = 10
c = 5 <== longest side is 5
sub in 5 for c in the 3rd equation
3a + 1 = 2c
3a + 1 = 2(5)
3a + 1 = 10
3a = 10 - 1
3a = 9
a = 3 <== shortest side
now sub in 5 for c and 3 for a back into the first equation
a + b + c = 12
3 + b + 5 = 12
b + 8 = 12
b = 12 - 8
b = 4 <== other side
Answer:
-5
