Answer:
2x-10
Step-by-step explanation:
Multiply BOTH x and -5 by 2
When the radical terms are the same, just focus on the numbers that are in front of them so it's really just 6 - 9 and you get -3 (third root of 2b)
Answer:
b
Step-by-step explanation:
because it is
Answer:
No
Step-by-step explanation:
We can check with the Pythagorean Theorem.
a^2 + b^2 = c^2
a and b are always the smaller sides, the legs
c is the longer side, the hypotenuse
3^2 + 3^2 > 6^2
9 + 9 > 36
18 < 36
18 is not greater than 36, therefore this triangle can not have the side lengths 3, 3, and 6.
