Answer:
x = 3
y = 8
Step-by-step explanation:
In the given triangle FGH,
m∠F + m∠G + m∠H = 180° [Triangle sum theorem]
60° + 90° + m∠H = 180°
m∠H = 30°
If the given triangles FGH and TUV are congruent, their corresponding sides will be equal in measure.
m∠F = m∠T
7y + 4 = 60°
7y = 56
y = 8
GH ≅ UV
8x - 12 = 12
8x = 24
x = 3
D. The answer has to be 2,000, eliminating A and C. B doesn't even use the original equation, as well as incorrectly solving the method, so D is the correct answer, even if you don't understand the principles.

Step-by-step explanation:
Answer:
Option (b) is correct.
The solution of the quadratic equation 
is -7 and 3
Step-by-step explanation:
Consider the given quadratic equation
This can be rewritten as, 
We can solve the quadratic equation using middle term splitting method,
4x can be written as 7x-3x , we get,
Taking terms common, we get,
Thus, 
Thus, we get (x-3)= 0 or (x+7)= 0
this gives x = 3 or x = -7
Thus, the solution of the quadratic equation is -7 and 3
