The diagram below shows a box that is 19 inches long, 9 inches wide, and 7 inches tall. Toby wants to cover the entire box with paper. He will need enough paper to cover an area of at least- A 734 in. 2
B 342 in. 2
C 266 in 2
D 126 in.2

no one knows lol

step-by-step explanation:

the correct answer is 1: 2

step-by-step explanation:

hope this your welcome : )

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
