The correct answer to the question above would be letter C. The diagonal piece of pipe would be 289 feet. I got this through drawing a line in the two opposite corners of the rectangle, giving me a right triangle. Then, i proceeded to using the pythagorean theorem (since two sides are given and the hypotenuse is the one missing.
If you need to solve this equation you can multiply the both side of equation on (-1). Like that
<span>2 = (-x);
-1·2 = (-1)·(-x)
if you multiply negative and </span><span>positive </span>you'll have negative,
if you multiply negative and <span>negative you'll have </span><span><span>positive. So
</span>
</span>-2 = x. or
x = -2.
The answer is -2.
Answer:
C is correct
Step-by-step explanation:
Your answer would be x=8
4=√2x ( switch the sides )
√2x=4 ( square both sides )
2x=16 ( divide both sides by 2 )
x=8
