Answer:

Yes

Step-by-step explanation:

Solving for 2x+14=8

Subtract 14 on both sides: 2x= 8-14

2x = -6

Divide by 2: x = -3

-3 = -3

Answer:

They are equivalent

Step-by-step explanation:

2x+14 = 8

Lets solve for x

Subtract 14 from each side

2x+14-14 = 8-14

2x = -6

Divide by 2

2x/2 = -6/2

x = -3

They are the same

How to do a Pythagorean theorem question

Aleonysh [2.5K]

A Pythagorean theorem question is one that deals with the side lengths of a RIGHT triangle.

When solving a question you would use the formula, a^2 + b^2=c^2

A and B are both of the sides that aren’t the hypotenuse.

C is distinguishable from a and b as it is the side opposite from the 90 degree angle. (90 degree angles are formed by perpendicular lines)

Hope this helps :)
