(-7c + 4b) + 2b (-7c - 6b) = -1
Answer:
-q
Step-by-step explanation:
We know that we are trying to find an expression equivelant to p - q:
p - q can be p - 1q
We can then put parenthesis around -1q:
p + (-1q)
We then can simplify:
p + (-q)
Using Pythagoras' theorem (a² + b² = c²), the correct answer is:
D. h² = a² - x²
Because a would be the hypotenuse, but h is not, so you have to rearrange the equation.
