PLEASE HELPS NEED THIS DONE BEFORE 3 O CLOCK

1)Jerome noticed the following house numbers on his street:

305, 318, 331, 344

The house numbers follow a pattern. Which expression can be used to determine the nthnth house number on his street?

A) 292 +13n

B) 292n

C) 292n + 13

D) 13(n + 292)

2) A polynomial expression is shown below.

Answer 1

Jerome noticed the following house numbers on his street:

Answer 292 +13n

A polynomial expression is shown below. What is the value of m?

Answer -3

What is the domain of the function shown below

Answer −8 ≤ x <3and 4 ≤ x <8

Answer 2

1) Put n=2 in each of the offered expressions and see which one gives you 318 (the second house number).
A) 292 + 13*2 = 318 . . . . a good candidate
B) 292*2 = 584 (nope)
C) 292*2 + 13 = 597 (nope)
D) 13(2 + 292) = 3822 (nope)
The appropriate choice is ...
A) 292 +13n

2)The squared term in the product is 2mx^2. The squared term in the given expression is -6x^2. Comparing the coefficients, we have
2m = -6
m = -3
The appropriate choice for the value of m is ...
C) -3

3) The end point of one segment matches up with the beginning of the next except in the region 3 ≤ x < 4.
The appropriate choice is ...
B) -8 ≤ x < 3 and 4 ≤ x < 8
