Answer:
top ? = 16
Explanation:
top question mark:
notice how 5 X 6 X 4 = 10 X 12 and how 3 X 2 X 10 = 6 X 10
the outside numbers multiplied together is equivalent to ten times the inside number
8 X 20 X 1 = ? X 10
8 X 20 X 1/10 = 16
? = 16

An example of 17.3 subtracting polynomial expressions question is solve for 2q² - q - 8) - (2 q² + q - 4).
<h3>What is polynomial expressions?</h3>
A polynomial is known to be a type of an expression that is made up of variables, constants and exponents. They are often combined using the mathematical terms such as addition, subtraction, etc.
2 q² - q - 8) - (2 q² + q - 4)
= (2 q² - q - 8) + (-2 q² - q + 4)
Then you have to rewrite subtraction as addition and then Group like terms together;
= (2 q² - 2 q²) + (-q - q) + (-8 + 4)
= -2q - 4
