Will give brainliest! explain how you got this answer! 2x + y = −4 y = 3x + 2

2x + y = −4 so y = -2x - 4

y = 3x + 2

now you have

y = -2x - 4

y = 3x + 2

-2x - 4 = 3x + 2

-5x = 6

x = -6/5

x = - 1.2

y = 3(-1.2) + 2

y = -3.6 + 2

y = -1.6

Answer

(-1.2 , -1.6)

dc=6 square root of 3 and ac is 12 square root 3

c and d

step-by-step explanation:

square root of 3/2 = 18/c

cross multiply to get 18*2=√3*c

36/√3 * √3/√3 = c

c= 36*√3/3

c=12√3
