Without finding the quotient, is the value of the expression ( -3&1/3 + 3&1/2 ) ÷ ( -1/4 ) positive or negative? Explain

4th option is correct xy=-10

if this was to u plzz mark me the brainliest

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.  

11.2

step-by-step explanation:

when doing tangent the tangent of the angle is equal to the opposite side from the angle over the adjacent side to the angle.

tan43 = x / 12

move 12 over by multiplying each side by 12

12tan43 = x

x = about 11.2
