Answer:

Step-by-step explanation:

p² + 14p + 49 = p² + 2 * 7p + 7²

Ivanshal [37]

Answer:

<h3>k = 10</h3>

Step-by-step explanation:

Given the equation;

$\dfrac{k}{100} = \dfrac{1}{10}$

We are to find the value of k.

Cross multiply;

$\dfrac{k}{100} = \dfrac{1}{10} \\10 \times k = 100 \times 1\\10k = 100\\$

Divide both sides by 10

$10k/10 = 100/10\\k = 10$

Hence the value of k is 10
