x^2 - 4x - 12 = 0
factors
(x - 6)(x + 2) = 0
Set (x - 6) and (x + 2) equal to 0 and solve for xx.
x - 6 = 0; x = 6
x + 2 = 0; x = -2

answer
x = -2 or x = 6

Since −12-12 does not contain the variable to solve for, move it to the right side of the equation by adding 12 to both sides.x2−4x=12Move 12 to the left side of the equation by subtracting it from both sides.x2−4x−12=0Factor x2−4x−12x2-4x-12 using the AC method.(x−6)(x+2)=0Set x−6 equal to 0 and solve for x.x=6Set x+2 equal to 0 and solve for x.x=−2The solution is the result of x−6=0 and x+2=0x=6,−2

The population of Weston is 4320. The town’s records show that 45 percent of the population are males, and 2 3 23 of these males

lbvjy [14]

Answer:

In Weston 1,296 males are married

Step-by-step explanation:

step 1

Find out the number of males

Multiply the total population by 45%

$45\%=45/100=0.45$

$4,320(0.45)=1,944\ males$

step 2

Find out the number of males that are married

Multiply the number of males by 2/3

$\frac{2}{3}(1,944)=1,296\ males\ married$

therefore

In Weston 1,296 males are married
