Answer:
When x=4
P(x) =4 - 4(4)^2 + 4(4) -5
=4 - 4(16) + 16 -5
=4 - 64 +11
= -60 + 11
= -49
Answer:
fourth option
Step-by-step explanation:
Given
f(x) = (x + 1)(x + 4)(x - 7)
To find the x- intercepts let f(x) = 0, that is
(x + 1)(x + 4)(x - 7) = 0
Equate each factor to zero and solve for x
x + 1 = 0 ⇒ x = - 1
x + 4 = 0 ⇒ x = - 4
x - 7 = 0 ⇒ x = 7
x- intercepts are (- 1, 0 ), (- 4, 0 ), (7, 0 )
Answer:
![\frac{1}{18}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B18%7D)
Step-by-step explanation:
Answer:
125
Step-by-step explanation:
Sum of Exterior Angles must add to 360 so
![60 + 70 + 40 + 65 + x = 360](https://tex.z-dn.net/?f=60%20%2B%2070%20%2B%2040%20%2B%2065%20%2B%20x%20%3D%20360)
![235 + x = 360](https://tex.z-dn.net/?f=235%20%2B%20x%20%3D%20360)
