Replace the letters a, b, and c with the numbers 3, 4, and 5 to make a true statement, 2a+2a=bc

Step-by-step explanation:

In this problem, we are expected to provide an outcome to a true statement that the left-hand side of the equation is the same as  the right-hand side

2a+2a=bc

Given that

a= 3,

b= 4,

c= 5.

We can substitute these values for a, b, and c in the given expression to see if the LHS and the RHS of the given expression are equal

2(3)+2(3)=4*5

6+6=20

12=20

The answer is FALSE because 12 is not equal to 20

i believe the correct answer is option 4.principalities were small territories that were run by russian rulers.

which statement correctly defines principalities in northern asia in the 1200s? principalities were small territories that were run by russian rulers.

hope i could ! : )

the solution of the equation is 2.23 ⇒ answer b

step-by-step explanation:

* lets revise the meaning of exponential function

- the form of the exponential function is y = ab^x, where a ≠ 0, b > 0 ,  

  b ≠ 1, and x is any real number

- it has a constant base b

- it has a variable exponent x

- to solve an exponential equation, take the log or ln of both sides,  

  and solve for the variable

* lets solve the problem

∵

- the base is 7 and the exponent is x

- insert ㏑ in both sides

∴

- use the rule

∴ x ㏑(7) = ㏑(77)

- to find x divide both sides by ㏑(7)

∴

* the solution of the equation is 2.23 to the nearest 2 decimal places
