The answer to your question is GCF = 3

Step-by-step explanation:

Polynomial

                -15y⁴ + 12y² - 9y

Process

1.- Find the Greatest common factor of the coefficients

                15   12   9      2

                15    6    3     2

                15    3    3   3

                 5    1      1     5

                  1

The GCF of the coefficients is 3

2.- Find the GCF of the variables

                 y⁴   y²   y   here, the GCF is the variable with the higher exponent

                                   repeated in all the terms

   The GCF = y

3.- Conclusion

The GCF of the polynomial is 3y              

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,
