They are both multi-step problems.If that's not the answer then I don't know.
Answer:
d
Step-by-step explanation:
The sum to n terms of a geometric sequence is
= ![\frac{a(r^{n}-1) }{r-1}](https://tex.z-dn.net/?f=%5Cfrac%7Ba%28r%5E%7Bn%7D-1%29%20%7D%7Br-1%7D)
where a is the first term and r the common ratio
Here a = 3 and r = 12 ÷ 3 = 4 , thus
= ![\frac{3(4^{8}-1) }{4-1}](https://tex.z-dn.net/?f=%5Cfrac%7B3%284%5E%7B8%7D-1%29%20%7D%7B4-1%7D)

= 65536 - 1 = 65535 → d

Step-by-step explanation:
<u>Step 1: Define</u>
2(3x + 4) - 3(x - 1) = x - 1
<u>Step 2: Solve for </u><em><u>x</u></em>
- [Distributive Property] Distribute: 6x + 8 - 3x + 3 = x - 1
- Combine like terms: 3x + 11 = x - 1
- [Subtraction Property of Equality] Subtract <em>x</em> on both sides: 2x + 11 = -1
- [Subtraction Property of Equality] Subtract 11 on both sides: 2x = -12
- [Division Property of Equality] Divide 2 on both sides: x = -6
972. Keep in mind the ratio of square feet to square inches is 144:1 as opposed to 12:1
Only √3 is an irrational number, since you can't write it as a fraction
