Answer:
The answer for Factorization is (x+6)(x-2) = 0 or Solving for x is 2 and -6.
Step-by-step explanation:
x² - 12 = -4x
Factorisation :
x² + 4x - 12 = 0
x² - 2x + 6x - 12 = 0
x(x-2)x + 6(x-2) = 0
(x+6)(x-2) = 0
Solve for x :
(x+6)(x-2) = 0
x + 6 = 0
x = -6
x - 2 = 0
x = 2

Answer:
maybe u should have paid attention in class buddy
Step-by-step explanation:
L
X=hours master worked
y=hours apprentice worked
62x+40y=492
if master worked 3hours more than apprntice
x=3+y
sub 3+y for x
62(3+y)+40y=492
expand
186+62y+49y=492
186+102y=492
minus 186 both sides
102y=306
divide both sides by 102
y=3
sub back
x=3+y
x=3+3
x=6
master electrician worked 6 hours
6*62=372
master electrician earned $372
Total fees = 1.95% of 336,500 + $100 + 0.3% of 10% of 336,500 = (0.0195 x 336,500) + $100 + (0.003 x 0.1 x 336,500) = 6,561.75 + 100 + 100.95 = $6,762.70
