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, $n =$ ± $17$

Х-y=5 x-2y=3 Can someone help me

tatiyna

First multiply -1 on the top to cancel X

It will give u:

-X+Y=-5
X-2Y=3 which gives u

y=2

Now, plug in the y (one of the equation it doesn’t matter which one) to solve for X

X-2=5
X=7
