The correct expressions are:
5.3d
5d+0.3d
5(d+0.06d)
Since he is purchasing 5 towels that have a cost of d dollars each, the cost of the towels is given by 5d.
However, to add 6% tax, we multiply this by 0.06 and add it to the price without tax:
5d+0.06(5d)
Simplifying this, we have 5d+0.3d = 5.3d.
All of the correct answers simplify to this expression.

Step-by-step explanation:
The cosine of an angle in a triangle can be calculated as a relation between the adjacent side and the hypothenuse. So, in this case the adjacent side of θ is 24 and the hypothenuse is 26.
Then:
cos(θ) = 24/26 = 12/13
Answer:
S = 85cm^2
Step-by-step explanation:
The surface area of a square pyramid is given by the following formula:
where it has taken into account the sum of the area of a square and four triangles:
h: slant height = 6cm
b: base = 5cm
By replacing in the formula you obtain:
hence, the surface area is 85cm^2
