C+a+b=p
move a to the other side
sign changes from +a to -a
C+a-a+b=p-a
C+b= p-a
move +b to the other side
C+b-b= p-a-b
Answer:
C= p-a-b
Answer:
A
Step-by-step explanation:
In normal situations, the answer would be B, but because of the context of the question, it talks about the phone's remaining battery life. Which means anything between 0 and12 will be our domain.

Explanation:
(In order avoid issues with the Brainly censor, we're going to rename point F as point G in this answer. Wherever you see G, you can use F in your own response to this question.)
<u><em>General Approach</em></u>
The perpendicular lines tell you these are right triangles. There are a few ways to show right triangles are congruent, one of which is the "HL theorem." It requires you show the hypotenuse and one leg are congruent in the two triangles.
Here, the hypotenuses, DE and AG, are shown as congruent. All that remains is to show one leg is congruent. We have no information about legs BE and CG, but we do have information that will let us show legs AC and DB are congruent.
_____
<em><u>Proof</u></em>
1. DE ≅ AG, DC ≅ AB, GC⊥AC, EB⊥DB . . . . given
2. m∠EBD = 90°, m∠GCA = 90° . . . . definition of perpendicular lines
3. CD + CB = DB . . . . segment sum theorem
4. AB + CB = DB . . . . substitution property of equality (CD→AB)
5. AB +CB = AC . . . . segment sum theorem
6. DB = AC . . . . transitive property of equality
7. ΔACG ≅ ΔDBE . . . . HL theorem
1/2n + 15 = 9 <== ur equation
1/2n = 9 - 15
1/2n = - 6
n = -6 * 2
n = - 12 <== ur solution
Answer:
8 + x^3.
Step-by-step explanation:
The cube of a number is that number to the power 3.
