Please help, I don’t understand.

To find the answers, you basically have to use trial and error. I'm not sure how else to find them.

Anyways, grouping up "6+12" as one group and "2^2-2+1" as the other leads to

-----------------------------

For the next problem, you'll need 2 sets of parenthesis, but this time one set of parenthesis is inside another one. The (6+12) becomes 18, which divides by 2 to get 9. Squaring that leads to 81 and then you subtract off 1 to get 80.

well my understanding of this question is they want you to use the y=14.1x -2.3 and put the coordinates they gave you onto the line segment of   y=14.1x -2.3

step-by-step explanation:

b. 6

step-by-step explanation:

we are given the table representing an exponential function.

we can see from the table that, as x is increasing, the value of y is increasing in the power of 6.

i.e. the following relation is obtained,

x = 1, y = 6

x = 2, y = 36 =

x = 3, y = 216 =

x = 4, y = 1296 =

x = 5, y = 7776 =

so, the geometric series obtained is .

thus, the common ratio is given by = = 6.

hence, the common ratio is 6.
