Im so confused can you please show your work

-29

Step-by-step explanation:

It is asking you to find the answer for the expression by plugging stuff in!

Given: 2(m+1) - n³

"Plugging" in: 2(-2 + 1) - (3)³

Simplfying: 2(-1) - 27

Distribute: -2 - 27

Simplfying: -29

(Edit: aaa, ty for my second Brainliest haha, have a nice day and keep learning everyone!)

2(m+1)-n I where m= -2 and n=3

2(-2+1) -(3)³

2(-1) - 27

-2+(-27)

= -29

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
