Same as before
total=(2w+75)(2w+35)=4w²+220w+2625
pool=75 times 35=2625
minus pool from total
4w²+220w+2625-2625=4w²+220w
The 15th term of the arithmetic sequence 
Option B is correct
The nth term of an arithmetic sequence is given as:
The first value, a = 22
Since 
The common difference, d = 3
The 15th term of the arithmetic sequence = 64

Answer:
22 and 158
Step-by-step explanation:
Supplementary angles add to 180. This is means there is a small and large angle. Adding together, they make 180.
- "the larger angle measures four degrees more than seven times the measure of a smaller angle" is represented as 7x+4.
- "x represents the measure of the smaller angle" is represented as x.
x + 7x+4 =180
8x+4=180
8x=176
x= 22
This is the measure of the smaller angle. The larger angle is 7(22)+4 = 158
23(x)-85
Substitute 12 for x
23(12)-85
276-85
