For 9) Joy is correct because a square has four sides so it is always a quadrilateral. Quadrilaterals do not always have equal sides so they are not always squares.
For 10) The answer is C. To be a parallelogram, a shape must have two sets of parallel sides, which all 3 shapes have.
For 11) The answer is A. A square has four sides and four right angles, so it is always a rectangle.
Hope this helped :)

Explain why √3x+2 = -16 has no solution.
pogonyaev
The equation you wrote has no solutions since the left hand side is equal to 6x-10 and the right hand side is equal to 6x+8. Setting them equal we get -10=8 which is obviously wrong.

The geometry of the hybrid orbitals about a central atom with sp3d hybridization is:________
Lyrx [107]

For sp3d hybridized central atoms, the only possible molecular geometry is trigonal bipyramidal.

Hybridisation (or hybridization) is a process of mathematically combining two or more atomic orbitals from the same atom to form an entirely new orbital different from its components and hence being called as a hybrid orbital.

In this case, if all the bonds are in place, the shape is also trigonal bipyramidal.

In chemistry, a trigonal bipyramid formation is a molecular geometry with one atom at the center and 5 more atoms at the corners of a triangular bipyramid.

Bond angle(s): 90°, 120°

Coordination number: 5

Point group: D3h
