Use PEMDAS. Parenthesis, Exponents, Multiply, Divide, Addition, Subtraction.
So, you'd distribute 5 into the parenthesis, leaving you with 9+20x+20, then add like terms. 20x+29

Answer:
<em>The compound inequality that shows the voltage amount the necessary range is
</em>
Step-by-step explanation:
Loni needs between 3.5 and 7.2 volts of energy, not inclusive, to make an experiment work correctly.
That means, <u>the voltage amount should be either greater than 3.5 volts or less than 7.2 volts</u>.
Suppose, the amount of voltage is
volts to make the experiment work correctly.
Now, Voltage amount is greater than 3.5 volts means:
or 
and voltage amount is less than 7.2 volts means: 
Thus, the compound inequality by combining the above two inequalities will be: 
How can you use a bar diagram to check the accuracy of the solution to a ratio or rate problem<span>? ... To see which bar is higher... the higher the bar the soloution if the ratio ... If the ratio of problems she finished to problems she still had left was 8 : 1, how many homework problems did she have total?</span>
