Answer:
A and C
Step-by-step explanation:
solving the equations
A
x² - 4 = 0 ( add 4 to both sides )
x² = 4 ( take square root of both sides )
x = ± 
= ± 2 ← required solution
B
x² = - 4 ← has no real solutions
C
4x² = 16 ( divide both sides by 4 )
x² = 4 ( take square root of both sides )
x = ± = ± 2 ← required solution
D
2(x - 2)² = 0 , then
x- 2 = 0 ( add 2 to both sides )
x = 2 ← not the required solution
The variable we need to isolate is P. In order to do so, we add a / 3w on both sides.
P =
Answer:
C. you can not prove that the triangles are congruent
Step-by-step explanation:
- The answer can not be SAS becuase although the congruent angle is not in between the two congruent sides.
- It can not be AAS because only one angle is congruent.
- It can not be SSS because all three sides are not congruent.
There would be no solutions. 13x cancels each other out in the equation, so you would have no X all together.
