Step (1)
x²+7x8=0
Step (2)
(+8)(x - 1) = 0
Step (3)
*+8 = 0 or 1-1=0
Step (4)
8 or
X-1
a. The solution is incorrect. Identify the step that does not follow logically from
the previous step. Explain why it is incorrect.
A the last step is incorrect because X+8=0 is not equal to 8 it is equal to
-8

b. Solve the quadratic equation correctly using any method, and show that

your solution(s) are correct
What method do you prefer to solve the equation? Explain your response,

I need help with the second two

-8

step-by-step explanation:

452,489 to the nearest thousand is 452,000

answer set (b) 0.5, 3/4 80% is in order from least to greatest.  

step-by-step explanation:

in order to compare rational numbers to each other, it is much easier if they are in the same form.   typically, the best form in which to evaluate rational numbers is in decimals.   in order to convert a percent to a decimal, you would divide the given percentage by 100.   you can also accomplish the conversion by moving the decimal point over two places to the left.   for example, the decimal value of 80% is 80/100, or 0.8.   in order to convert a fraction to a decimal, you need to divide the numerator by the denominator.   for example, 3/4 is 0.75.   so, for choice (b) 0.5 3/4 (0.75), 80% (0.8) is the only choice in which the numbers are in order from least to greatest.
