Answer:
Step-by-step explanation:
A_{n+1}=14*A_{n}
A_{1}=8
A_{1+1}=14×8=112
A_{2}=112
A_{3}=14*A_{2}=14×112=1568
A_{4}=14*A_{3}=14×1568=21952
A_{5}=14*A_{4}=14×21952=307328
He uses 2 feet of the yard or... 4/6 hope this helped :3
He will need double the amount of what he would need for the one garden.
Answer:
![a: (a-b)(a+b);b: (a-b)(a^{2}+ab+b^{2}); c: (a^{2} +2ab+b^{2}); d: (a+b)(a^{2}- ab+b^{2})](https://tex.z-dn.net/?f=a%3A%20%28a-b%29%28a%2Bb%29%3Bb%3A%20%28a-b%29%28a%5E%7B2%7D%2Bab%2Bb%5E%7B2%7D%29%3B%20%20c%3A%20%28a%5E%7B2%7D%20%2B2ab%2Bb%5E%7B2%7D%29%3B%20d%3A%20%28a%2Bb%29%28a%5E%7B2%7D-%20ab%2Bb%5E%7B2%7D%29)
Step-by-step explanation:
Given the expressions all that is required is to expand them (using the distributive property) to see which answers they match up to:
For a:
For b:
For c calculate the square of a sum: ![(a+b)^2=a^2+ab+ab+b^2](https://tex.z-dn.net/?f=%28a%2Bb%29%5E2%3Da%5E2%2Bab%2Bab%2Bb%5E2)
(add like terms) c: ![a^2+2ab+b^2](https://tex.z-dn.net/?f=a%5E2%2B2ab%2Bb%5E2)
For d: ![(a+b)(a^2-ab+b^2)=a^3-a^2b+ab^2+a^2b-ab^2+b^3](https://tex.z-dn.net/?f=%28a%2Bb%29%28a%5E2-ab%2Bb%5E2%29%3Da%5E3-a%5E2b%2Bab%5E2%2Ba%5E2b-ab%5E2%2Bb%5E3)
![=a^3+b^3](https://tex.z-dn.net/?f=%3Da%5E3%2Bb%5E3)
Answer:
<u>Problem 4:</u> Option C, 32
<u>Problem 5:</u> You need to have the 2 and the x combine. Make the table 2x than 16.
<u>Problem 6:</u> x = 17
<u>Problem 7:</u> She drew a 2, x and an 16. Instead you must have 2x and 16. 2x + 16 = 50
Step-by-step explanation:
<u>Problem 4</u>
2 + x + 16 = 50
x + 18 - 18 = 50 - 18
x = 32
Answer: Option C, 32
<u>Problem 5</u>
You need to have the 2 and the x combine. Make the table 2x than 16.
Answer: You need to have the 2 and the x combine. Make the table 2x than 16.
<u>Problem 6</u>
2x + 16 - 16 = 50 - 16
2x / 2 = 34 / 2
x = 17
Answer: x = 17
<u>Problem 7</u>
She drew a 2, x and an 16. Instead you must have 2x and 16. 2x + 16 = 50
Answer: She drew a 2, x and an 16. Instead you must have 2x and 16. 2x + 16 = 50
