Answer:
x= -3
x= -5
Step-by-step explanation:
x^2 + 8x + 15 = 0
find which 2 numbers when multiplied equal 15 and when added equal 8
they are 3 and 5
(x+3)(x+5)
x+3 =0
x+5=0
x= -3
x= -5
Since it's a wall, I'm guessing it will only have access to half the circle? Therefore:
<em>Circle area formula: </em>πr²
<em>Radius:</em> 12/2 = 6ft
<em>Our case:</em>
(π * 6²)/2 =
36π/2 =
18π = 56.55ft²
Answer:
x = 5 and x = 
Step-by-step explanation:
To find the zeros equate f(x) to zero, that is
(2x - 1)(x - 5) = 0
equate each factor to zero and solve for x
2x - 1 = 0 ⇒ x =
x - 5 = 0 ⇒ x = 5
D because none of the other statments are correct and it's the only one that lines up with the data.
