Answer:
x² - 4
Step-by-step explanation:
Step 1: Write expression
(x + 2)(x - 2)
Step 2: FOIL
x² + 2x - 2x - 4
Step 3: Combine like terms
x² - 4
2/18
3/27
4/36
5/45
6/54
Take any number let's say 9
Then 9/9 = 1
Or 9/9 = 1/1
Then if you multiply the bottom half of those by 9, you get
9/9 becomes 9/81
and
1/1 becomes 1/9
So to generate any fraction equivalent to 1/9
take any number and write it as one, i.e. 5/5 = 1 (or 1/1)
and then multiply the bottom part by 9 = 5/45
Answer:
14:9
Step-by-step explanation:
you cant simplify so just put : in between the numbers and boom! ur ratio is 14 to 9 or 14:9
hope this helps :D
Answer:
First term=3
Second term =-2
Third term=18
Fourth term=-62
Fifth term=258
Sixth term=-1022
Step-by-step explanation:
an=(-4)^(n-1) + 2
First term: a1=(-4)^(1-1) + 2
a1=(-4)^0+2
a1=1+2
a1=3
Second term:a2=(-4)^(2-1)+2
a2=(-4)^(1)+2
a2=-4+2
a2=-2
third term:a2=(-4)^(3-1)+2
a2=(-4)^(2)+2
a2=-4 x -4 + 2
a2=16+2
a2=18
Fourth term: a4=(-4)^(4-1)+2
a4=(-4)^3 +2
a4=-4x-4x-4+2
a4=-64+2
a4=-62
Fifth term:a5=(-4)^(5-1)+2
a5=(-4)^4+2
a5=-4x-4x-4x-4+2
a5=256+2
a5=258
6th term:a6=(-4)^(6-1)+2
a6=(-4)^5+2
a6=-4x-4x-4x-4x-4+2
a6=-1024+2
a6=-1022
Answer:
<h2><em><u>
a) is correct</u></em></h2>
3n + 5
1. Substitute the numbers
3(5) + 5 = 15 + 5 = <em><u>20</u></em>
2. Substitute the second number
3(6) + 5 = 18 + 5 = <em><u>23</u></em>
<h2><u><em>
b) Numbers are 8 and 16.</em></u></h2>
This is because I realized I got the number of 4 last because I did 1*2 = 2.
Then I did 2*2 = 4.
So you have to multiply by two to get the next number. Or you can put it to the 4th or 5th exponent of 2.
1. 1
2. 1*2 = 2
3. 2*2 = 4
<h2><em><u>
4. 4*2 = 8</u></em></h2><h2><em><u>
5. 8*2 = 16</u></em></h2>
