Answer:
a. S = 3n + 2
b. There while be 62 squares.
Step-by-step explanation:
We know the first term of this sequence is 5. To figure out the equation, subtract the following term from the previous. Do you see a common difference?
8 - 5 = 3
11 - 8 = 3
14 - 11 = 3
We're seeing a constant difference of 3 (which makes this an arithmetic sequence), but the first term is 5. That mean something is being added to make the first term 5. Subtract 3 from 5 to get 2. This means 2 is being added to every multiple of 3, which leads us to the equation: S = 3n + 2.
To find the 20th term of this sequence, substitute n for 20 and do the operations.
S = 3(20) + 2
<em>Multiply 3 by 20, then add 2.</em>
S = 62
The 20th term will have 62 squares.
Answer:
C
Step-by-step explanation:
Answer:
<h2>1 t-shirt cost $5</h2><h2>hat costs $2</h2>
Step-by-step explanation:
8 t-shirts and a hat cost £42.00
3 t-shirts and a hat cost £17.00.
<u>difference</u>
5 t-shirts cost $25
1 t-shirt cost $5
3 t-shirts cost $15
3 t-shirts and a hat cost £17.00.
<u>difference</u>
hat costs $2
32.50+4.50x
You are going to pay $32.50 no matter what, that is what you pay for basic cable. $4.50 is what you pay for the extras, so depending on how many premium channels you want, you will pay $4.50 for every extra channel, which is why it is 4.50x because the x is how many premium channels you purchase that month.
<h2>g(x)= (x + -5)² minus -8= 33 </h2><h2 />
