Factor the expression using the gcf. the expression 8x+2 factored using the gcf is

Simplifying

8x2 + -18y2

Factor out the Greatest Common Factor (GCF), '2'.

2(4x2 + -9y2)

Factor a difference between two squares.

2((2x + 3y)(2x + -3y))

Final result:

2(2x + 3y)(2x + -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,
