Answer:
f(x) = x² + 7x + 12
Step-by-step explanation:
Given that the zeros are x = - 3 and x = - 4, then the factors are
(x - (- 3)) and (x - (- 4)), that is (x + 3) and (x + 4)
f(x) is the product of the factors, that is
f(x) = (x + 3)(x + 4) ← expand using FOIL
f(x) = x² + 7x + 12
Since the surface area is the (edge length) ^2
if the (e. l) is multiplied by 1/2,
the surface area is multiplied by (1/2)^2 = 1/4
Answer:
15/2
Step-by-step explanation:
The equation would be 425 x .83(12) + 250 because 425 is what he has at first, then times .83 which is what returns back to him each month, which .83 is multiplied by 12 which is how many months that are in a year plus 250 which is what he adds on after each year
The answer would be D) 2.25
Sorry if I get it wrong
540/x=100/18
<span>(540/x)*x=(100/18)*x - </span>we multiply both sides of the equation by x
<span>540=5.5555555555556*x - </span>we divide both sides of the equation by (5.5555555555556) to get x
<span>540/5.5555555555556=x </span>
<span>97.2=x </span>
x=97.2
<span>now we have: </span>
<span>18% of 540=97.2</span>
