Which of the two could be side lengths of the same triangle? A. 12 cm, 17 cm, 25 cm
or
B. 8 yd, 13 yd, 17 yd.

I think both

A. 25 yd, 12 yd, 17 yd

B . 8yd,  13 yd,  17 yd

Step-by-step explanation:

12<17+25            8<13+17

17<12+25            17<13+8

25<17+12            13<17+8

  but

12>25-17                and

25>17-12              8>17-13

17>25-12              17>13-8

                             13>17-8

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571
