Which expression can be used to find the volume of the rectangular prism in cubic centimeters? Image shows a prism with a base area of 245 square cm and a height of 85 cm. A. 85 + 245 B. 85 × 85 × 245 C. 85 + ( 85 × 245 ) D. 85 × 245

they can both be solutions depends on the equation

step-by-step explanation:

what is the equation? ?

the answer is c.

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

answer is  

c.
