This is pretty much saying that if x = -3, then solve for the equation, so (-3)^2 - 4(-3) = 9 - 12 = -3
The answer is B. In 10 hours, the phone would completely lose its charge.
Y=-10(10)+100=-100+100=0
Answer:

Step-by-step explanation:
From the question we are told that:
Length of each side
Let the triangle be divide by two form a right angle triangle with base angles as
(angle of perpendicularity) and
(angle on each vertices of an equilateral triangle)
Generally the equation for the Altitude X is mathematically given by
Trigonometric Rule



Scale : 1 cm = 2.5 ft
1 cm = 2.5 ft
0.5 cm = 2.5 x 0.5 = 1.25 ft
Circumference = πD = π(1.25) = 3.93 ft
Answer: 3.93 ft
You said that A = (s-2) 180
Divide each side by 180 : A/180 = s-2
Add 2 to each side: A/180 + 2 = s
