Given
x - 9 > 3 ( add 9 to both sides )
x > 12

However, 11 is less than 12 and is not in the solution set → A
Answer:
Length 34 cm
Width 8 cm
Step-by-step explanation:
Let
x-----> the length of the rectangle
y----> the width of the rectangle
we know that
The perimeter of rectangle is equal to
P=2(x+y)
P=84 cm
so
84=2(x+y)
42=x+y ----> equation A
x=4y+2 -----> equation B
substitute equation B in equation A and solve for y
42=(4y+2)+y
5y=42-2
y=40/5=8 cm
Find the value of x
x=4y+2 ----> x=4(8)+2=34 cm
The dimensions are
Length 34 cm
Width 8 cm
Answer:
no
Step-by-step explanation:
An arithmetic sequence has a common difference between adjacent terms. Here, the differences are ...
The differences are different, not common, so this is NOT an arithmetic sequence.
