Answer:
x² + 4x + 3
Step-by-step explanation:
Supose answer A is true...
Because the division of
{ (x -5) * (x² + 4x + 3) } / (x -5) = (x² + 4x + 3)
.... you should only have to check if
(x -5) * (x² + 4x + 3) = x³ - x² - 17x - 15
That is what to do:
(x -5) * (x² + 4x + 3)
using FOIL method you get...
x³ + 4x² + 3x - 5x² -20x - 15
x³ + (4x² - 5x²) (-20x + 3x) - 15
and this is exactly x³ - x² - 17x - 15
Hence Answer A is correct.
Answer:
√61
Step-by-step explanation:
The speed is the magnitude of the velocity.
= sqrt (6^2 + 5^2) = √61
ANSWER
The coefficient of y is
EXPLANATION
The first equation is
We can rewrite this equation in the slope intercept form to get,
We divide through by 10 to get,
The slope of this line is
and the y intercept is
Let
be the coefficient of y in the second equation.
Then, we have
We rewrite this equation too in slope intercept form to get,
Dividing through by
gives,
For the two equations to have infinitely many solution, then they must have the same slope and y intercept.
This means, that,
This implies that
Therefore the coefficient of y must be 2.
Answer:
7/10 x 2/5 = 14/50 = 7/25
Step-by-step explanation:
mutipily 7 and 2 that gives you 14 and mutilpily 10 and 5 that gives you 50 = 14/50. In simplest form the answer is 7/25.
