When x = 3 and y = 5, by how much does the value of 3x2 – 2y exceed the value of 2x2 – 3y ?

Step-by-step explanation:

Put x = 3 and y = 5 to the expressions 3x² - 2y and 2x² - 3y.

Use PEMDAS:

PParentheses first

EExponents (ie Powers and Square Roots, etc.)

MDMultiplication and Division (left-to-right)

ASAddition and Subtraction (left-to-right)

3x² - 2y

3 · 3² - 2 · 5 = 3 · 9 - 10 = 27 - 10 = 17

2x² - 3y

2 · 3² - 3 · 5 = 2 · 9 - 15 = 18 - 15 = 3

Make the difference:

17 - 3 = 14

1/4 and 8/3 because:

the reciprocal if 4 is 1/4 because 4 is used as 4/1 and the opposite of that is 1/4. the opposite of 3/8 is 8/3 so that is the answer.
