To do this problem, you will need to know the side lengths of the triangle. If you have those, just plug them in for a, b, and c and evaluate the square root.
Here is an example. If the sides are 3, 4, 5.
It would be:
The 6 is in the formula because it is the semi-perimeter (half).
Answer:
The slope is undefined
Step-by-step explanation:
When graphed, the two points form a vertical line, since we can't divide the slope by zero thw slope is considered as undefined
Answer:
4.0/5
12
The second statement.
Step-by-step explanation:
Any increasing exponential function will always eventually be greater than any other non-exponential function.
1. Answer=66cards
Lets use the variable 'x' to represent the number of baseball cards in Keith's collection that he started with. The following equation can be made.
(x+6)/2=36
multiply both sides by 2
x+6=72
subtract 6 from both sides
x=66 cards
2. Answer=$12
Lets use the variable 'a' to represent Sara's allowance. The following equation can be made:
(a/2)+7=13
subtract 7 from both sides
a/2=6
multiply both sides by 2
a=$12
