Fourteen decreased by three times four

3 times a number is 3x

decreased by 14 is '- 14'

is 4 is '= 4'

So we have:

3x - 14 = 4

Add 14 to both sides:

3x = 18

Divide 3 to both sides:

x = 6

Step-by-step explanation:

D. there is nothing so we skip

A. there is nothing so we skip

S. 14 - 12 = 2

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.
