With math you, will give brainliest !

A

7*(1)(14) = 98 Not the right answer. I have done what is inside the brackets first. (5 - 4) = 1; (5 + 9)= 14; 7 * 1 * 14 = 98 which is not 6

B

7 * [1 * 5] + 9 = 44; 7 * 5 + 9 = 35 + 9 = 44 Also not 6

C

7*[5 - 20 + 9] = - 42; Not 6 as well 7*[14-20] = 7*-6 = - 42

D

7*5 - [20 + 9] = 35 - 29 = 6

Answer D

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,

step-by-step explanation:

descending order means to order the polynomials from the term with the largest exponent to the term with the smallest exponent.  

therefore, the correct answer is d.
