Answer:
Eric forgot to add 2 to both sides.
Step-by-step explanation:
He forgot to add 2 to both sides so that he cancel out the -2 from the equation. Then the equation would become 2/5v=6 the you would divide those two and your answer would be 1/15.
What are the answer choices?
but in my head, I would see substitution as the answer but like I said it would depend on the answer choices
It’s a right angle triangle so u have it use Pythagorean theorem.
c^2 = a^2 + b^2
25^2 = 20^ 2 + b^2
625 = 400 + b^2
b^2 = 225
b = 15
X = 15
You can not solve that equation.
