Hello there! :)
Answer:
The last option.
Step-by-step explanation:
If w = -2 and v = -8:
Substituting these into the equation w² - v + 1 would look like:
(-2)² - (-8) + 1
When finding the square of a negative number, parenthesis must be used because:
-2² = -4, whereas (-2) = 4.
When subtracting a negative number, parenthesis also need to be used:
-(-8) = +8.
The corresponding equation that is equivalent to this is the final equation listed, or the fourth option.

Answer:Let's assume x be the smaller number.
Given that, The greater number is 4 more than the smaller number.
So, greater number= x+4.
It's also given that, The sum of two numbers is 52. Which means sum of x and x+4 must be equa to 52. Hence,
x + (x + 4) = 52
Step-by-step explanation:
It only equals positive 12, that symbol means it equals positive and negative 12
The answer is 2/4 I believe
