Given that t<span>he science department buys the equipment shown in the table below.

Item                      Time Bought
Microscopes          every 5 years
Safety goggles      every 4 years
Test tubes             every 2 years

Given that they bought all three items this year. The number of years it will take for them to buy all three items again in the same year is given by the LCM of 5, 4, and 2.

5 = 1 x 5
4 = 1 x 2 x 2
2 = 1 x 2

LCM = 1 x 2 x 2 x 5 = 20.

Therefore, they will buy all three items again in 20 years.

F(x) = x^2. What is g(x)?
MatroZZZ [7]

Answer:

D. g(x)=(3x)^2

Step-by-step explanation:

For function g(x), it displays the point (1,9) as part of the function. If (x,y), then we can plug those into the available answers. Plug 1 in for each x value in the function and whichever one equals 9 will be your answer. This is only true for g(x)=(3x)^2.
