Answer:

By the Pythagorean theorem
AB = √(12²+5²) = √169 = 13 units

$\frac{AD}{AB} = \frac{BD}{BC} \ \to \ BC= \frac{AB*BD}{AD}= \frac{13*12}{5}= 31.2 \ units$

URGENT WILL MARK BRAINLIEST Show your work and solve for x and y. 3x + y = 8 2x + 4y = 12

mars1129 [50]

3x+y=8--(1)

2x+4y=12

x+2y=6--(2)

(1)×1 and (2)×3

$\\ \rm\Rrightarrow 3x+y=8$

$\\ \rm\Rrightarrow 3x+6y=18$

Subtract both

$\\ \rm\Rrightarrow -5y=-10$

$\\ \rm\Rrightarrow y=\dfrac{-10}{-5}$

$\\ \rm\Rrightarrow y=2$

Put the value in eq(2)

$\\ \rm\Rrightarrow x+2(2)=6$

$\\ \rm\Rrightarrow x+4=6$

$\\ \rm\Rrightarrow x=6-4=2$
