Answer:
D
Step-by-step explanation:
Because A isn' at all right and B, and C equal the same but D = 36 So the sides are 18 each side.
The restrictions for the equation is that the denominator can not be zero. So the restrictions for x would be what values make the denominator zero.
7x^2 + 6x = 0
factor
x(7x + 6) = 0
multiply any number by 0 and you get 0. So either x = 0 or 7x+6 = 0
since there's a x in the numerator x/x = 1 so this will not be a restriction. Then the only restriction is:
7x+6 = 0
7x = -6
x = -6/7
-4x+0y=-8
=> x=2
substitute 2 into either function for y
it will come out the same and u will have solution
Note, if slopes or coefficient of x are the same => no solution because lines are parallel
Follow! and give me a brainliest plz
