Answer:
A
Step-by-step explanation:
We have:
And we want to isolate x₂.
So, let’s first remove the denominator by multiplying both sides by it:

Now, we can subtract x₁ from both sides. So:
Finally, we will multiply both sides by -1. So:
Hence, our answer is A.
Answer:
5cm
Step-by-step explanation:
c^2=a^2+b^2
b^2=square root c^2-b^2
=square root 13^2-12^2= 5
Answer:
b=7
