If you factor it the answer would be (2x+1)(2x+5). Hope this helped.
Answer:
The directrix of parabola is the line x = +10.
Step-by-step explanation:
The general form of parabola is given as
where the directrix is the vertical line x = - p .
If p > 0, then parabola opens to the right.
If p < 0 then parabola opens to the left.
Now here, the given equation is
Representing the given equation in standard form:
⇒ p = -10
So, the directrix of the parabola is x = - p = - (-10) = 10
or, x = + 10
Hence, the directrix of parabola is the line x = +10.
You can find the answer by multiplying 0.875 * 32
so 28...
Answer: the answer is 19.4m
Step-by-step explanation:
Answer:
See below.
Step-by-step explanation:
We know that and we want to prove that .
Statements Reasons
1) Given
2) A) Vertical Angles Are Congruent
3) B) Substitution Property
4) C) Alternate Interior Angles Converse*
*We know that alternate interior angles are congruent when two parallel lines are cut by a transversal. So, the converse states that if the two alternate interior angles are congruent, the the two lines must be parallel.
Further Notes:
I'm not sure why they did more than necessary. Since , they are corresponding angles. Then by the Corresponding Angles Converse, p must be parallel to r.
