Answer:
12
Step-by-step explanation:
the lcm of 3 and 4 is 12
1) Answer: The part of the quadratic formula tells us whether the quadratic equation can be solved by factoring is b^2-4ac
2) 4x^2+6x+2=0
ax^2+bx+c=0; a=4, b=6, c=2
b^2-4ac=(6)^2-4(4)(2)=36-32
b^2-4ac=4
Answer: b^2-4ac=4

Answer:
A) 8, 15, 17.
Step-by-step explanation:
Right triangle obey the Pythagorean theorem. Thus, we choose the two smaller numbers (being the cathetus) and if after applying the P. Theorem we get the biggest of each option (the hypotenuse) that means that those numbers could be the sides of a right triangle.
The Pythagorean theorem states that: ![a^2+b^2=c^2](https://tex.z-dn.net/?f=a%5E2%2Bb%5E2%3Dc%5E2)
Thus:
![\sqrt{a^2+b^2}=c](https://tex.z-dn.net/?f=%5Csqrt%7Ba%5E2%2Bb%5E2%7D%3Dc)
Option A:
→ 17 = 17 OK!
Option B:
→ 10 ≠ 12 NO
Option C:
