Hey there! I'm happy to help!

Numbers with the same variable and exponent are like terms and can be simplified.

$2y^5+4y^5=6y^5$ (variable is y, exponent is 5)

$-3y^3-5y^3=-8y^3$ (variable is y, exponent is 3)

So, our final simplified form is $6y^5-8y^3$ .

Have a wonderful day! :D

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.
