N = 3 and 6/7, because if we add both sides by 32, then the equation will look like 14n = 54, and if we divide both sides by 14 (to isolate the variable), then 54 divided by 14 is 3 and 6/7. Hope if helps :D

Question number 8. Prove that 3 + √5 is an irrational number.​
Marina86 [1]

Answer :

Let's assume the opposite of the statement i.e., 3 + √5 is a rational number.

\\  \sf \: 3 +  \sqrt{5}  =  \frac{a}{b}   \\  \\   \qquad \: \tiny \sf{(where \:  \: a \:  \: and \:  \: b \:  \: are \:  \: integers \:  \: and \:  \: b \:  \neq \: 0)} \\

\\  \sf \:  \sqrt{5}  =  \frac{a}{b}  - 3 =  \frac{a - 3b}{b}  \\

Since, a, b and 3 are integers. So,

\\ \sf \:  \frac{p - 3b}{b}  \\  \\  \qquad \tiny \sf{ \: (is \:  \: a \:  \: rational \:  \: number \:) } \\

Here, it contradicts that √5 is an irrational number.

because of the wrong assumption that 3 + √5 is a rational number.

\\

Hence, 3 + √5 is an irrational number.

Dad’s truck is 15 feet long. The trailer it tows is 40% longer the truck. How long the trailer?
elena-14-01-66 [18.8K]

Answer:

21 Feet Long

Step-by-step explanation:

You just reverse how you find a percentage.

1) 40 / 100 = .40

2) .40 * 15 = 6

3) 6 + 15 = 21

I did it this way because I need to find what 40% is to 15. But the trailer isn't 40% of the truck, it's 40% longer than the truck. So, we must add those 2 numbers together getting 21 Ft.
