-5 - (-7) what’s the answer

2

Step-by-step explanation:

We would distribute the '-' into the '-7' to yield the second step.

Hope this helps.

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.

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.
