Step-by-step explanation:
= - 4
= a* + (3- 1) d*
- 4 = a + 2d . . . . . . . . .(i)
= - 29
= a + ( 8 - 1) d
- 29 = a + 7d . . . . . . . . (ii)
subtracting equations (i) and (ii)
25 = 5d
d = -5
placing d = -5 in equation (i)
a - 10 = -4
a = 6
For an arithmetic Progtession
= a + (n - 1)d
= 6 + (n- 1)-5
= 6 - 5n + 5

Answer:
B. 12x + 8
Step-by-step explanation:
2x + 5 + 4x - 1 + 2x + 5 + 4x - 1
<em>Combine like terms.</em>
6x + 5 - 1 + 2x + 5 + 4x + 1
8x + 5 - 1 + 5 + 4x - 1
12x + 5 - 1 + 5 - 1
12x + 10 - 1 - 1
12x + 10 - 2
<em>Subtract 2 from 10 to get 8.</em>
12x + 8
The perimeter of the rectangle is 12x + 8, which is B.
Domain is the x-values.
Scenarios where positive integers are appropriately used for the domain of the function:
<span>The function c(p) represents The cost for P people to attend the movies. (number of people can either be 0 going upwards)
</span><span>the function m(t) represents the miles driven over T hours (hours always start with 1.)
</span><span>the function t(m) represents the average high temperature for a given number of months (number of months always start with 1)
</span><span>the function p(w) represents the prophet of a farmer who sells whole watermelons (count of whole watermelon starts with 1)
</span>
<span>the function h(n) represents the number of person-hours it takes to assemble n engines in a factory (number of engines always start with 1)</span>
