Answer:
Basic Definitions of Geometry
A collinear set of points is a set of points all of which lie on the same straight line.
A noncollinear set of points s a set of three or more points that do not all line on the same straight
line.
A Line has no end points.
A Ray has one end point.
. Line Segment has two end points
Congruent segments are segments that have the same measure.
The Midpoint of a line segment is a point of that line segment that divides the segment into two
congruent segments.
The Bisector of a line segment is any line, or subset of a line that intersects the segment at the midpoint.
An Angle is a set of points that is the union of two rays having the same endpoint.
1. (3 + xz)(–3 + xz)
2. (y² – xy)(y² + xy)
3. (64y2 + x2)(–x2 + 64y2)
Explanation
The difference of 2 squares is in the form (a+b)(a-c).
(3 + xz)(–3 + xz) = (3 + xz)(xz -3)
= (xz + 3)(xz - 3)
= x²y²-3xy+3xy-9
=x²y² - 3²
(y² – xy)(y² + xy) = y⁴+xy³-xy³-x²y²
= y⁴ - x²y²
(64y2 + x2)(–x2 + 64y2)= (64y²+x²)(64y²-x²)
= 4096y⁴-64y²x²+64y²x²-x⁴
= 4096y⁴ - x⁴

Answer:
side of base, a = 10.1 inches, height, h = 40.1 inches
Step-by-step explanation:
Volume of rectangular solid, V = 4096 cubic inches
Let the side of base is a and the height is h.
surface area of the solid
So, h = 40.2 inches
Answer:
the opposite Angles sum up to give 180
Step-by-step explanation:
3y +3y = 180
y=30
if y = 30 the x = 55
are you clear?
