Answer:
D
Step-by-step explanation:
If (x - 5) is a factor of P(x) then P(5) = 0 ← Factor theorem
Given
P(x) = x³ - 5x² - x + 5, then
P(5) = 5³ - 5(5)² - 5 + 5 = 125 - 125 - 5 + 5 = 0
Since P(5) = 0 then (x - 5) is a factor of P(x)

Answer:
x=9
Step-by-step explanation:
-3 + 5x = 42
add 3 to both sides
5x=45
divide both sides by 5
x=9
Answer:
It forms an AP
AP : 71 , 73 , 75 , .................. 119
a = 71
d = 2
= a + (n-1)d
119 = 71 + (n-1)2
n-1 = (119 - 71)/2
n = 24
= n/2 × (a +
)
= 24/2 × (71 + 119)
= 12 × 190 = 2280
