2x+4=10-4x
-2x+4=10
-2x=6
X=-3
Note that the area of a square is: A = s² (s being side). Also note that all the sides of the square are congruent and have the same measurement.
Plug in 37 for A
37 = s²
Isolate the s. Note the equal sign. What you do to one side, you do to the other. Root both sides
√37 = √s²
s = √37
Change the root to a decimal
s = √37 = ~6.1 (rounded to the nearest tenth)
6.1 in is your answer
hope this helps

Answer:
The solution of the equation is
⇒ 3rd answer
Step-by-step explanation:
* Lets explain how to solve this problem
- The function f(x) = e^x is called the (natural) exponential function
- The natural logarithm (㏑), or logarithm to base e, is the inverse
function to the natural exponential function
∵
is an exponential function
∴ We can solve it by using the inverse of e (㏑)
- Remember:
# 
# 
- Insert ln in both sides
∴ 
∵ 
∴ 2x + 5 = ㏑(4)
- Subtract 5 from both sides
∴ 2x = ㏑(4) - 5
- Divide both sides by 2 to find x
∴ 
* The solution of the equation is
