the answer is B. 72 mm^2 because
9x4.5=40.5
then
7x4.5=31.5

40.5+31.5=72.0 mm^2
Answer:
, 
Step-by-step explanation:
One is given the following equation:
Factor this expression:
Set the equation equal to (0), then use the zero-product property to solve for (x). The zero product property states that any number times zero equals zero. Thus, one can apply this here to solve for (x):
Inverse operations,
Answer:
answer is number 3 you can check on a calculator
Step-by-step explanation:
Answer:
Option 2 would be the better deal, as long as they would only pay $ 87.37 for the smart TV.
Step-by-step explanation:
To determine which deal is better before taxes, the aforementioned discounts must be made at the original prices and their results compared, through the following calculations:
1)
320 - (320 x 15/100) = X
320 - 48 = X
272 = X
2)
349.49 - (349.49 x 75/100) = X
349.49 - 262.11 = X
87.37 = X
3)
280 = X
Therefore, as can be seen, option 2 would be the better deal, as long as they would only pay $ 87.37 for the smart TV.
