Which of the following triangle side lengths will form a triangle? 2 cm, 5cm, 6 cm
1 cm, 4 cm, 7 cm
3 cm, 6 cm, 10 cm
6 cm, 7 cm, 13 cm

vertical=18cm horizontal=18cm hypotenuse=25.5

step-by-step explanation:

"standard form:

3x2 + 14x − 10 = 0

solutions based on quadratic formula:

x1   = −14 − √ 142 − 4×3×(−10) /   2×3   = −14 − 2 × √ 79 /   6   ≈ −5.296

x2   = −14 + √ 142 − 4×3×(−10) /   2×3   = −14 + 2 × √ 79 /   6   ≈ 0.629

i think the answer is c sorry if it's wrong
