Step-by-step explanation:
The polynomial functions A) and C) have a leading coefficient of 3, but C) has a lower degree.
f ( x ) = 3 x² - 21 x + 30
3 ( x² - 7 x + 10 ) = 3 ( x² - 5 x - 2 x + 10 ) =
= 3 ( x ( x - 5 ) - 2 ( x - 5 )) = 3 ( x - 2 ) ( x - 5 ) = 0
x = 2 and x = 5 ( roots )
Answer:
C ) f ( x ) = 3 x² - 21 x + 30
Answer:
A
Step-by-step explanation:
The tangent- tangent angle x is half the difference of the measures of the intercepted arcs.
minor arc = 360° - 254° = 106° , then
x =
(254 - 106)° =
× 148° = 74° → A
Answer:
The answer is 1 1/2 = 3/2 1 = 2/2 LCD=2
The first eqaution is multiplying the first number by 5 then the next is multiplying the first number by 6 then 7 i believe the last one would be 8x8 which is 64
