-  \frac{2}{3}  - ( -  \frac{4}{6} ) =  \\

-  \frac{2}{3}  +  \frac{4}{6}  =  \\

-  \frac{2}{3}  +  \frac{2 \times 2}{2 \times 3}  =  \\

-  \frac{2}{3}   +  \frac{2}{3}  =  0\\

Triangle ABC has sides with lengths of 11, 18, and 8 units. Determine whether this triangle is a right triangle.​
Arturiano [62]

Answer:

Not a right triangle.

Step-by-step explanation:

If this triangle is a right triangle, then the Pythagorean theorem would work on it. According to the Pythagorean theorem, a^2+b^2=c^2, so c would always be greater than a or b. In this scenario, the greatest number here is 18, so c = 18. Since a or b don't matter if given both legs, we have the following equation that may or may not be equal: 8^2+11^2=18^2. We know 8 squared is 64, and 11 squared is 121, and 18 squared is 324. This means that 64+121=324 according to the Pythagorean theorem, and since 64 + 121 = 185, and 185 does not equal 324, the Pythagorean theorem does not work and the triangle is not a right triangle.

John is solving x^2 + 4x + 8=0 by completing the square. Which step would be part of John's solution.?
SOVA2 [1]

Answer:

(x + 2) ^{2}  =  - 8

Step-by-step explanation:

{x}^{2}  + 4x + 8 = 0 \\  {x }^{2}  + 4x =  - 8 \\  {x}^{2}  + 4x + 4 =  - 8   + 4 \\ ( x + 2)^{2}  =  - 4
