Answer:

n = 5

Step-by-step explanation:

3 x (n+1)² = n² + (n+2)² + 34

3n² + 6n + 3 = n² + n² + 4n + 4 + 34

n² + 2n - 35 = 0

(n - 5) (n + 7) = 0

n is a positive number

n = 5

check: 5, 6, 7

6 x 6 x3 = 108

(5 x 5) + (7 x 7) + 34 = 25 + 49 + 34 = 108

What is 8/15 plus 2/5 equal to

anastassius [24]

We have to add 8/15 to 2/5.

To add two fractions we have to make them have the same denominator, so we have to convert 2/5 to have a denominator of 15. To do this, we have to multiply 2/5 by 3 and then we can add the fractions:

$\begin{gathered} \frac{8}{15}+\frac{2}{5} \\ \frac{8}{15}+\frac{2}{5}\cdot\frac{3}{3} \\ \frac{8}{15}+\frac{6}{15} \\ \frac{14}{15} \end{gathered}$

Answer: 14/15
