Answer:
The answer is 3.
Explanation:
Factors of 18:
1, 2, 3, 6, 9, 18.
Factors of 21:
1, 3, 7.
The highest number that both sets contain is 3, so the GCF will be 3.
If the rectangle ABCD is similar to rectangle EFGH, side CD is proportional to the side
C. GH
The order of the letters in naming the rectangle gives us which sides are adjacent in rectangle and which sides correspond to the other rectangle.
(x+3)(x-3)
x*x=x^2
x*-3=-3x
3*x=3x
3*-3=-9
where’s where he most likely messed up
x^2-3x+3x-9
the correct answer is x^-9
Answer:
that will be .... x=2,y=1 so that will be (2,1)
