Answer:

Answer:

Hexagonal pyramid DOES NOT have any rectangular faces

Step-by-step explanation:

Given some solids we have to choose that one which DOES NOT have any rectangular faces

Pentagonal prism has total 7 faces out of which two faces are pentagons and 5 are rectangular.

Hexagonal pyramid is a pyramid with a hexagonal base upon which are erected 6 isosceles triangular faces.

It has no rectangular face.

Rectangular prism is a solid with 6 rectangular faces also known as cuboid.

Square pyramid is a pyramid with 1 square base. As every square is a rectangle.

we can say 1 rectangular face.

Hence, Hexagonal pyramid DOES NOT have any rectangular faces.

Option B is correct.

Write an inequality for the given statement: The sum of x and 25 is less than 75.

Answers

That statement would be best express by " x + 25 < 75 ". Since the statement says the sum of x and 25, thus, it will be x + 25. Then it also states that the sum is less than 75, so the best expression would be " < 75".
