Correct question is;
Factor out the GCF from the given polynomial. 10x³ + 16x² - 18x. (Type your answer in factored form.)
Answer:
GCF = 5x² + 8x - 9
Step-by-step explanation:
The given polynomial is;
10x³ + 16x² - 18x
First thing is to inspect the coefficients and see the greatest number that all three can be divided by evenly without remainder.
The greatest number is 2.
Secondly let's inspect the variables to see what we can factor out.
They all contain x. Thus, x is a factor.
Thus, we will divide each term by 2x to obtain the GCF of the polynomial.
GCF = (10x³/2x) + (16x²/2x) - (18x/2x)
GCF = 5x² + 8x - 9
Answer:
Step-by-step explanation:
tanx=12/18
x=arctan(12/18)
tan(90-x)=12/(a+5)
tan(90-arctan(12/18)=12/(a+5)
a+5=12/tan(90-arctan(12/18))
a=12/tan(90-arctan(12/18))-5
a=3
3n + 15 >= 3n + 8 distribution.
3n - 3n >= 8 - 15 arrange the like terms.
0 >= -7 combine the like terms.
