Answer:
what solid??????
Step-by-step explanation:
Answer:
W=5
Step-by-step explanation:
40+4w=12w
-4w -4w
40= 8w
÷8 ÷8
5=w
Let's start with a picture.
We see RST is smaller, and BC is parallel to but in the opposite direction to its corresponding segment ST. Both have slope -1.
If we look at the difference of points (technically called vectors but we don't have to go there) we get
C-B=(-2,2)
T-S=(1,-1)
Without further calculation we can see T-S is half the length of C-B.
The problem asks for a dilation followed by a reflection. We know the dilation scale is k=1/2 because the new triangle is half the size.
After dilation we get A'B'C':
A'(3,2), B'(-1,0), C'(-2,1)
We see now we need a reflection that flips the coordinates x and y. That's the +45° line through the origin, namely y=x.
Answer: k=1/2, y=x
When the end of division is zero.
Okay so we gotta do whats in the lines first so 6+14 that’s gonna be 20 but the add the 70 and it’s gonna be 90
