De construit triunghiul ABC, daca BC=5cm, BG=3cm, CG=4cm, unde G e centru de greutate a triunghiului

1 x=22.52

2: 65/39=604+39x

65x-39x=604

26x=604

x=604/26

×=23.23

answer is c

step-by-step explanation:

81/12=324/x

x=48

"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

1/8 is left? add a bit more info plz
