Two stacks of quarters are shown. Both stacks have the same amount of quarters. The statement below uses the Cavlieri's principle to explain why the volumes of these two stacks of
quarters are equal.
the sections made by planes
from their respective bases are always equal, then the
volumes of the two solids are equal.
Which of the following pair of statements can be use to fill in the empty boxes above?

in geometry nation its in two solids of equal altitude, parallel to and at the same distance.

Step-by-step explanation:

just got it wrong :(

-2x + 7 = 7

subtract 7 from both sides.

-2x = 0

divide both sides by -2.

x = 0

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
