The length of a rectangle is 2 units shorter than one-fifth of the width, x.
which expression represents the perimeter of the rectangle?
a. 2/5x−4
b. 12/5x−2
c. 12/5x−4
c. 2/5x−8

C.

Step-by-step explanation:

Width = x

Length = one fifth of width minus 2

Length =

Perimeter is given by the formula

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:

“a term can be a signed number, a variable, or a constant multiplied by a + sign or j sign. in , the terms are 5x , 3y and 8. when a term is made up of a constant multiplied by a variable or variables, that constant is called a coefficient.” i hope this you.
