A triangle has side lengths of (9.26 + 8.7) centimeters, (3.26 - 2.5) centimeters, and (9.8c + 1.6) centimeters. Which expression represents the perimeter, in
centimeters, of the triangle?

your question is incomplete, write all the numbers in the sequence that it tells you.  

step-by-step explanation:

answer: solve 5\cdot 2^x=2405⋅2  

x

=2405, dot, 2, start superscript, x, end superscript, equals, 240.

solution

to solve for xxx, we must first isolate the exponential part. to do this, divide both sides by 555 as shown below. we do not multiply the 555 and the 222 as this goes against the order of operations!

\begin{aligned} 5\cdot 2^x& =240 2^x& =48 \\ \end{aligned}  

5⋅2  

x

2  

x

​    

=240

=48

step-by-step explanation:

is there any other information given for this problem? this is not enough information.

example answer: "to determine if a sum is reasonable you can round each number to the nearest whole and compare the estimated sum to the actual sum."

hope this you and anyone else who needs the answer : ^)
