Answer:
x = -1 or
x = -7
Step-by-step explanation:
Given DAB and BCD are similar :
2x^2 + 7 = x^2 - 8x make the left side of equation 0 by exporting all terms to right side
2x^2 - x^2 + 8x + 7 = 0 add like terms
x^2 + 8x + 7 = 0
(x + 1) * (x + 7) = 0 in this case x is either -1 or -7
Answer: - 8, - 2
Step-by-step explanation:
Given that :
On a number line, point E has coordinate of - 5
And EG = 3
HENCE, the possible coordinates of G could be :
EG is the distance between point E and point G
Possible coordinates
E - G = EG
-5 - G = 3
-5 - 3 = G
-8 = G
Also:
G - E = EG
G - ( - 5) = 3
G + 5 = 3
G = 3 - 5
G = - 2
Heres some info i learend
s but its not complete maybe i guess
Terms. We combine em by adding. The numbers or subtracting the numbers that are multiplied times the radicals.
