A) f(x) = 2(3^x) is the answer
Answer:

Step-by-step explanation:
Let
x ----> the length of the third side of triangle in Lauren's sculpture
we know that
The <u><em>Triangle Inequality Theorem</em></u> states that the sum of any 2 sides of a triangle must be greater than the measure of the third side
Applying the Triangle inequality Theorem
1) 

Rewrite

2) 

therefore
The possible values of x are

Answer:
1 Solution.
Step-by-step
The answer is (5, -4) or x= 5, y= -4 making this system have 1 solution.
If you can please make mine the brainliest that would be much appreciated. Thanks!
Answer: 706.5
Step-by-step explanation:
First you have to square the radius. So for this question you multiply 5x5. That makes 25. Then you multiply that with pi ( 3.14 ) and that makes 78.50. Next you multiply it by 9, that makes 706.5.
12y+11 is the correct expression.
Product=result of multiplication
Increased= addition
The product of 12 and y increased by 11 is: 12y+11
