Answer:
The statements that correctly represent the scenario stated are:
B. because losing 8 pounds is represented as -8 and doing this for 3 months would be 3 groups of -8 or 3 x -8
D. because they showed the weight loss as a negative integer and then put those into groups of 4 each using the distributive property)
The error with the other 2 choices is that the negative number is not correctly representing which part of the problem is a decrease. The negative sign is placed on the number of groups of.
Step-by-step explanation:
Answer:
x² - 1 = 8
Step-by-step explanation:
Given the following algebraic expression;
x² - 1
When x = -3
Substituting the value of x, we have;
x² - 1 = (-3)² - 1
x² - 1 = 9 - 1
x² - 1 = 8
Method II.
x² - 1 = (x - 1)(x + 1)
Substituting the value of x, we have;
x² - 1 = (-3 - 1)(-3+ 1)
x² - 1 = -4(-2)
x² - 1 = 8
