10,000 square feet each floor.
Answer:
x ≤ 13/3
Step-by-step explanation:
4 - 3x ≥ -9
Isolate the variable, x. Treat the ≥ sign as an equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
First, subtract 4 from both side:
4 (-4) - 3x ≥ -9 (-4)
-3x ≥ - 9 - 4
-3x ≥ -13
Next, divide -3 from both sides. Note that when you divide by a negative sign, you must flip the sign:
(-3x)/-3 ≥ (-13)/-3
x ≤ (-13)/(-3)
x ≤ 13/3
x ≤ 13/3 is your answer.
~
4. 28.5 squared centimeter
5. height=18 ft
7. The triangle will be bigger. Since this scale factor is 4, then that means that the 2-D plane will be bigger.
8. The perimeter will get bigger.
You have five numbers 
Among them there is one negative number 
this number is smallest.
Note that
Since 6.25>6, then
and these numbers are less than 3
Note that
then 
and these numbers are greater than 3.
Therefore, the correct order from the smallest to the greatest is:
Masse of 1 proton: = 2.34 x 10⁻¹⁴
masse of 1000 protons = 2.34 x 10⁻¹⁴ x 1000 or 2.34 x 10 ⁻¹⁴ x 10³ =2.34 x 10⁻¹¹
