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

umka2103 [35]

Answer:

Option A, $n =$ ± $17$

Step-by-step explanation:

<u>Step 1: Add 29 to both sides</u>

$n^2 - 29 = 260$

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

$n^2 = 289$

<u>Step 2: Square root both sides</u>

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

$n =$ ± $17$

Answer: Option A, $n =$ ± $17$

Teresa says that the 3 most frequent measurements in order from shortest to longest are 3 1/4 inches,3 2/4 inches,and 3 3/4 inch

Blizzard [7]

Answer: We agreed with this.

Step-by-step explanation:

Since we have given that

$3\dfrac{1}{4}\ inches,\ 3\dfrac{2}{4}\ inches,\ 3\dfrac{3}{4}\ inches$

As we know that

$3\dfrac{1}{4}=\dfrac{13}{4}\ inches$

$3\dfrac{2}{4}=\dfrac{14}{4}\ inches$

$3\dfrac{3}{4}=\dfrac{15}{4}\ inches$

So, $\dfrac{13}{4}$

Hence, we agreed with this.
