Just complete h, i, j, k, L pleaseee I'll brainlist (don't forget working out)

h) -9

i) 2

j) -8

k) -5

l) 0

Step-by-step explanation:

h) 3(a+bc) = 3(5+4*-2) = 3(5-8) = 3(-3) = -9

i) (2a+b)/7 = (2*5+4)/7 = (10+4)/7 = 14/7 = 2

j) 8(3a-4b) = (8(3*5 - 4*4) = 8(15-16) = 8(-1) = -8

k) (abc-5)/9 = ((5*4*-2)-5)/9 = (-40-5)/9 = -45/9 = -5

l) (b+2c)/(a) = (4 + 2*-2)/(5) = 0/5 = 0

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i
