the area of a rectangle is 70 in² and the length of the rectangle is 3 in. longer than the width.
the area of a rectangle is found by multiplying the length times the width.
during the set up step of the five-step problem-solving plan, which equation would you set up to solve for the width? + 3 = 70

w(w+3)=70

3w = 70

w + 3w = 70

i dont know and i dont care for math bc it is a stupied subject

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
