If you would like to know what is y when x = 42, you can calculate this using the following steps:

x = 8 ... y = 20
x = 42 ... y = ?

8 * y = 20 * 42 /8
y = 20 * 42 / 8
y = 105

The correct result would be: y = 105 when x = 42.

Solve the equation n2 − 29 = 260 by using square roots.

umka2103 [35]

Answer:

Option A, $n =$ ± $17$

Step-by-step explanation:

Step 1: Add 29 to both sides

$n^2 - 29 = 260$

$n^2 - 29 + 29 = 260 + 29$

$n^2 = 289$

Step 2: Square root both sides

$\sqrt{n^2} = \sqrt{289}$

$n =$ ± $17$

Answer: Option A, $n =$ ± $17$
