Answer:
Step-by-step explanation:
A simple fraction (also known as a common fraction or vulgar fraction, where vulgar is Latin for "common") is a rational number written as a/b or {\displaystyle {\tfrac {a}{b}}}
b
a
, where a and b are both integers. As with other fractions, the denominator (b) cannot be zero. Examples include {\displaystyle {\tfrac {1}{2}}}
2
1
, {\displaystyle -{\tfrac {8}{5}}}−
5
8
, {\displaystyle {\tfrac {-8}{5}}}
5
−8
, and {\displaystyle {\tfrac {8}{-5}}}
−5
8
.
Answer: Non of the option.
Step-by-step explanation:
The given equation is
4x^3 - 6x^2 + 15x + 2 = 0
Let's test 1, if it's one of the root. I.e
If x = 1
4 - 6 + 15 + 2 = 15
Positive 1 is not a root to the equation
If x = - 1
-4 - 6 - 15 + 2 = - 23
Negative 1 is not a root
If x = 2
4x8 - 6×4 + 15×4 + 2
32 - 24 + 30 + 2 = 40
Positive 2 is not a root
If x = - 2
4×(-8) - 6×4 - 15×2 + 2
-32 - 24 - 30 + 2 = -84
Negative 2 is not a root
If x = 3
4×27 - 6×9 + 15×3 + 2
108 - 54 + 45 + 2 = 101
Since non of them tend to zero, non of the option is a root of the equation
Answer:
i think you have to count till you get to 4 or 3 then the remaining you plus with the 3
Identity property of multiplication
" of " means multiply
1/4 * 3.20/1...and just multiply....(1 * 3.20) / (4 * 1) = 3.20/4 = 0.8
or
1/4 = 0.25.....0.25(3.20) = 0.8
