In an attempt to factor using a GCF, Mia wrote 8x^2 + 4x = 4x (2x - 0), which is not correct. a) how could she check her work? b) what error did she make? c) what is the correct answer? (Not part of question) I believe the (2x - 0) should be (2x + 0) am I right?

i dont have an answer

step-by-step explanation:

chiken

step-by-step explanation:

10 b/c 5*2 =10

step-by-step explanation:

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
