Use gauss-jordan reduction to solve each of the following systems. (a) x1 + x2 = -1 4x1 – 3x2 = 3 (b) x1 + 3x2 + x3 + x4 = 3 2x1 – 2x2 + x3 + 2x4 = 8 3x1 + x2 + 2x3 – x4 = (c) x1 + x2 + x3 = 0 x1 - x2 – x3 = 0 (d) x1 + x2 + x3 + x4 = 0 2x1 + x2 - x₂ + 3x4 = 0 x₂ - 2x2 + x3 + x₂ = 0 |

konichiwa~! my name is zalgo and i am here to answer your anime-related question today. more than likely, kirishima would kill izuku, marry mino and kiss momo. all of this would be my opinion by the way. (and i am also a weeb lol)

(and do you think you can mark me as brainliest? i'd greatly appreciate it! arigato~! )

the answer is b: 18

step-by-step explanation:

use the pythagorean theorem to .

a^2+b^2=c^2

plug 18 for "r"

the 2 legs are 18 and 24

18^2+24^2=c^2

324+576=c^2

900=c^2

c=30

30-12=18

18 is the radius

2x + 8

plz mark brainliest i took the test
