Step-by-step explanation:
I just done it. it wasnt that hard
The general equation of second degree is
Ax²+By²+Gx+Fy+C=0 ------1
Now the given conditions are
A=1, B=0, C=0
Now,
putting in eq. 1
x²+Gx+Fy=0
x²+Gx= -Fy
For completing square, add both side (G/2)²
x²+Gx+(G/2)²=-Fy+(G/2)²
(x+G/2)²=-F(y-G²/4F)
Or
X²=-FY where X=x+G/2, Y=y-G²/4F
which is the standard eq. of parabola in XY-coordinate.

l xl means ± x .
then |2x+6| = ±(2x+6)
for positive no;
5 (2x+6) = 25
10x + 30 = 25
10x = -5
x = -1/2
for negative no;
5(-2x - 6) = 25
-10x - 30 = 25
-10x = 55
x = - 11/2
otherthan that I observed.
5 |2x + 6| means only consider about the positive number. i think it called as amplitude.
then you have to calculate by considering only considering plus value.
How ever in my openion is first method is correct. i have doubt about that. so you have to discuss your teacher dear. to find correct way.
Answer:
yes
Step-by-step explanation:
because side a (4) and side b (5) added together are greater or equal to side c (8)
