Can someone help me with this problem?
Answers
W: math homework reulary
A: B average or better
U:Univers 100%
W∩A= the answer
Or #(W∪A)+#(W∩A)=#W+#A
or #(W∪A)=100-40=60
==>60+x=48+55
==>x=43

(0-6)/(3-0) = (-6)/3 = -2
then slope intercept form is
y = mx + b
where m = slope and b is the y intercept
so now we have y = -2x + b
and the y intercept is when x = 0
so b = 6 from that point (0,6)
so we have the equation
y = -2x + 6
which is option C

The shapes formed by vertical, angled, and horizontal cross-section of a rectangular prism are: vertical: rectangle, horizontal: rectangle and angled: parallelogram
What is a cross-section of an object?
A cross-section of a solid is a plane figure obtained by the intersection of that solid with a plane. The cross-section of an object therefore represents an infinitesimal "slice" of a solid, and may be different depending on the orientation of the slicing plane.
Given is a rectangular prism, we need to define its cross-section
The vertical and horizontal cross-section are fairly straight forward. They are simply mirror images of the outward showing faces.
The angled cross-section is a bit more complicated and there's a lengthy proof involved, but long story short, the angled cutting plane divides the 3D solid such that we have 2 sets of lines that have the same slope (if we consider a 2D view), which leads to 2 sets of parallel sides.
Hence, the shapes formed by vertical, angled, and horizontal cross-section of a rectangular prism are: vertical: rectangle, horizontal: rectangle and angled: parallelogram

Imagine the shape is facing slightly towards your left
A left vertical cross section (perpendicular to the base) of the cuboid would result in a 10 by 6 rectangle
A right vertical cross section (perpendicular to the base) of the cuboid would result in a 6 by 4 rectangle
A horizontal cross section (parallel to the base) of the cuboid would result in a 10 by 4 rectangle
An angled cross section (through the middle) would also give a rectangle but the dimensions would be different. If the cut went from one '4' edge to the one in the opposite corner, the length of that would be found using Pythagoras
a² + b² = c²
6² + 10² = c²
36 + 100 = 136
√136 ≈ 11.66cm
11.66 by 4 rectangle
The shows that the resulting shape will always be a rectangle for these cross sections.
The only case in which it would not, would be if one of the faces of the cuboid was a square - in which case one of the cross sections would also be a square.

Answer:
A line ED parallel to one side of the triangle {CB} has intersected the other two sides of the triangle [AB and AC] making the sides proportional.
Step-by-step explanation:
The Triangle Proportionality Theorem states that:
If a line parallel to one side of a triangle intersects the other two sides then it divides those sides proportionally. The segments joining midpoints of the two sides of the triangle will be parallel to the third side and half the length.
This means if a line divides two sides of a triangle proportionally, then it is parallel to the third side.
In this case;
AD/AB =AE/AC is true because;
A line ED parallel to one side of the triangle {CB} has intersected the other two sides of the triangle [AB and AC] making the sides proportional.
The segments{AD,AB,AE,EC] joining the midpoints {D & E} of the two sides {AB & AC} of the triangle will be parallel to the third side BC and half the length.
