Answer:
Step-by-step explanation:
2{5x²-15+(-9xy²)}-(2y²+4x-xy²)+3x²
=2{5x²-15-9xy²}-(2y²+4x-xy²)+3x²
=10x²-30-18xy²-2y²-4x+xy²+3x²
=13x²-2y²-17xy²-4x-30

Answer:
Only Glass B is large enough
Step-by-step explanation:
For repetitive calculations, I like to use a calculator or spreadsheet. The attachment shows the volumes for the three glasses. Only Glass B has a volume that exceeds 75 cubic inches.
__
Note that Glass A has a diameter of 5 inches, so a radius of 2.5 inches.
In Euclidean plane geometry, a quadrilateral is a polygon with four edges (or sides) and four vertices or corners. Sometimes, the term quadrangle is used, by analogy with triangle, and sometimes tetragon for consistency with pentagon (5-sided), hexagon (6-sided) and so on.

The origin of the word "quadrilateral" is the two Latin words quadri, a variant of four, and latus, meaning "side".
Quadrilaterals are simple (not self-intersecting) or complex (self-intersecting), also called crossed. Simple quadrilaterals are either convex or concave.
The interior angles of a simple (and planar) quadrilateral ABCD add up to 360 degrees of arc, that is
{\displaystyle \angle A+\angle B+\angle C+\angle D=360^{\circ }.}
This is a special case of the n-gon interior angle sum formula (n − 2) × 180°.
All non-self-crossing quadrilaterals tile the plane by repeated rotation around the midpoints of their edges.
