Answer:
Step-by-step explanation:
<h3>Given</h3>
- P = 194
- l = 5w + 25
- l = ?, w = ?
<h3>Solution</h3>
<u>Perimeter formula</u>
<u>Substitute and solve for w:</u>
- 194 = 2(5w +25 + w)
- 194 = 12w + 50
- 12w = 144
- w = 144/12
- w = 12
<u>Find the length:</u>
A6 = -8
a15= -62
There are (15 - 6) terms in between, therefore 9 terms in between.
-8 to -62 ... there is a difference of 54
54 ÷ 9 = 6
Therefore it gets -6 each term.
a6 = -8, a7= -14, a8 = -20 ......
I confused ! I don't get what your trying to say please explain better !
