Which point is an x-intercept of the quadratic function f(x) = (x – 4)(x + 2)?

x=4,  x=-2

Step-by-step explanation:

f(x) = (x – 4)(x + 2)

To find the x intercepts, set f(x) = 0

0  = (x – 4)(x + 2)

Using the zero product property

x-4 = 0  and x+2 = 0

x-4+4 = 0+4     x+2-2 = 0-2

x=4 and x=-2

687.09 dollars       happy now

step-by-step explanation: 6870

1857 times .63 equals 1169.91 subtract that from 1857 you get 687.09

it will cost dollar $540

the living room is 3 which means if we divide 325/3 then we get $108

therefore if 1part of the living room cost $108 and 3 costed $325

then total 5part of the room will cost 5*108 which gives $540
