Answer:
it depends
Step-by-step explanation:
If 17 is the hypotenuse
if you are looking for the hypotenuse
The correct answer is: D) Subtracted like terms incorrectly
Step-by-step explanation:
Given
The terms 11.2y-7.4y need to be subtracted. But option b is to add them. We will add them and then solve the equation to see if its right.
So adding 11.2y-7.4y
Dividing both sides by 18.6
so by adding the terms instead of subtracting we get y=7.6.
this means that the error was adding 7.4y-11.2y instead of subtracting
The correct method will be:
Dividing both sides by 3.8
Hence,
The correct answer is: D) Subtracted like terms incorrectly
