(6x² - 3x - 7)(2x + 5)
12x³ + 30x² - 6x² - 15x - 14x - 35
12x³ + 24x² - 29x - 35
Answer:
50
Step-by-step explanation:
__
We make use of the special form for the difference of squares:
(a+b)(a-b) = a²-b²
We have been given that there are about 1.61 kilometers in 1 miles.
Let x represent a distance measured in kilometers and y represent the same distance measured in miles.
We can set two equations from the given information as:
(Number of kilometers in terms of number of miles)
(Number of miles in terms of number of kilometers)
Therefore, and will be our equations.
Answer:
—1=<x<-3
Since
X<-3
X>=-1
Not shaded means including.
If you convert it to a scientific notation it should be written out
7.962*10^-1.
Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the 10. The sign of the exponent will depend on the direction you are moving the decimal.
I hope this helps.
