A flag pole casts a 5 foot shadow while a nearby sign post casts a l 1/4 foot shadow. Find the height of the flagpole if the sign post is 4 feet high.

16 ft

Step-by-step explanation:

if the signpost is 4 ft and the shadow is 1.25 feet, the ratio of the shadow to post is 1.25:4 or 5/16

If the flagpole makes a 5 ft shadow, the equation for the height is 5/(5/16)

5/(5/16) = 5/0.3125 = 16

answer: give more info

step-by-step explanation:

the correct answer option is (2x-3)(2x+3).

step-by-step explanation:

we are given the following expression and we are to factorize it:

we are to find such factors that when multiplied they give a result of 36 (9 x 4 = 36) and when added they give a result of 0.

the two such factors of 36 are negative six and postive six.

factorizing the given expression to get:

therefore, the correct factorization of is (2x-3)(2x+3).
