First combine like terms
6c + 14 = 4c + 4, then subtract 4c from both sides
2c + 14 = 4, then subtract 14 from both sides
2c = -10, then divide both sides by 2
C = -5
The answer is B because C and D are not true. Angle-Angle theorem does not prove congruency. Hypotenuse-Leg does because having a hypotenuse means that the triangle is a right angle triangle, which means that 2 sides and an angle are congruent in the triangles. By Side-Side-Angle Theorem, the triangles are congruent.
Given:
Length of cloth = 9 yards
Length of pieces = 
yards each
To find:
The number of pieces of cloths after cutting.
Solution:
Let n be the number of required pieces.
Length of each piece is yards. So, the length of n pieces is 
yards.
The length of the whole cloth is 9 yards. So, yards must be equal to 9 yards.
Multiply both sides by 3.
Therefore, the Greata have 27 pieces of cloths.
Answer:
1) x+y=-2
x=-2-y
2) x-y=-8
substitude value of x
(-2-y)-y=-8
-2-2y=-8
-2y=-6
y=3
Substitute value of y in 1
x=-2-3
x=-5
