Question

is not b please someone help me

Answer 1

√j+√j+14=3√j+10
2√j+14=3√j+10
minus 2√j both sides
14=√j+10
minus 10 both sides
4=√j
squaer both sides
16=j

answer is D, 16

Answer 2

Answer: The answer is D. 16.

Step-by-step explanation: Now let's solve your equation by step-by-step-by-step in another way: $\sqrt{j}+\sqrt{j}+14=3\sqrt{j}+10$ to $2 \sqrt{j}+14=3\sqrt{j}+10$.

Step 1. Add -3√{j} to the both sides: $2\sqrt{j}+14+-3\sqrt{j}=3\sqrt{j}+10+-3\sqrt{j}$ to $-\sqrt{j}+14=10$.

Step 2. Add –14 to the both sides: $-\sqrt{j}+14+-14=10+-14$ to $-\sqrt{j}=-4$.

Step 3. Divide the both sides by -1 and now we can solve Square Root:

$\frac{-\sqrt{j}}{-1}=\frac{-4}{-1}$ to $\sqrt{j}=4$, $j=4^{2}$ (square both sides), and make sure to plug them in to make sure they work to check the answers; ∴, your answer is D. 16, please mark me as brainliest, and have a happy holidays! :D
