Answer:
x = ± 1
Step-by-step explanation:
Given
3(x² - 4) + 7 = - 2 ( subtract 7 from both sides )
3(x² - 4) = - 9 ( divide both sides by 3 )
x² - 4 = - 3 ( add 4 to both sides )
x² = 1 ( take the square root of both sides )
x² = ± 
= ± 1
Thus
x = - 1, x = 1

Step-by-step explanation:
B=brackets
i= indices
D= division
M=multiplication
A= addition
S= subtraction
7x10000/5x100/6x1
7x10000=70000/500/6
70000/500=140/6= 23.33

OOF no one answered in 4 days?! wow
Answer:
A
Step-by-step explanation:
First I converted the fractions into decimals to make it easier to solve.
2 1/2 —> 2.5
1 3/4 —> 1.75
Then I added the two decimals together.
2.5 + 1.75 = 4.25
Then I divided this number by 100 (the number of cups in one bag)
100/4.25=23.529
With this equation I know that one bag lasts 23 full days.
This is almost a month, and so it would not make sense for the answers to be B, C, or D.
Hope this helped
