The answer to the question is 29
For this question we need to know how the modulus function works
if the value inside the modulus function is positive then it opens with positive sign .
if the vale inside the the modulus function is negative then it opens with negative sign .
Putting the value of d as 3 in the given equation |-3d-6|+|-5-d²|
we get-
|-3×3-6|+|-5-9|
On simplifying we get
|-9-6|+|-14|
Since both the modulus function are having negative value both will open with negative sign-
-(-15)+-(-14)=29
Hence the answer is 29
