Answer:
(b) commutative property
Step-by-step explanation:
The "simplified" expression has the positions of the last two terms in the sum swapped. The property of addition that lets you change the order of the terms is the <em>commutative property of addition</em>.
Answer:
y=3
Step-by-step explanation:
Assuming this is an enlargement where EFGH is enlarged to ABCD then the former is the object and the latter is the image. If so then
scale factor(k) of the enlargement=image length/corresponding object length
k=3/2
Therefore, y=4.5/k
y=4.5/(3/2)
y=3
If we take the assumption another way and say ABCD is reduced to EFGH then the former is the object and the latter is the image.
In that case,
k=⅔
y=4.5×k
y=3
In either case y=3units
all you have to do is find the coordinates of the segment ratio
the answer would be (9,1)
