Answer: e. 2h + 3 = 10; h = 3.5h
Explanation:
Jane can run 2 miles per hour. (2h)
He need to run 10 miles in total and has done 3 so far. (+ 3 = 10)
The equation can be written:
2h + 3 = 10
2h = 7
h = 7/2 = 3.5

Answer:
<h2>Pythagorean Theorem: a^2 + b^2 = c^2</h2>
But what is the actual question?
Answer:
If the roots of an equation are x = -1 ± i, it means that the factorized form of that equation is: (x + 1 + i)(x+ 1 - i) = 0.
Using the distributive property, we have:
(x + 1 + i)(x+ 1 - i) = x^2 + x - ix + x + 1 - i + ix + i + 1
Combining like-terms and simplifying:
⇒ x^2 + x + x + 1 + 1 = x^2 + 2x + 2 = 0
Therefore, the stament is correct. If the roots of an equation are x = -1 ± i, then the equation is: x^2 + 2x + 2 = 0.
