False.
y= 3(1)+1= 4
y= 3(2)+1=7 not 5
y= 3(3)+1=10 not 6
X(a+b)-y(a+b)
*factor out (a+b)*
=(a+b)(x-y)
-133/2=-66.5
If we take the upper and lower round of that number we will get the 2 consecutive numbers that make -133.
Therefore the answer is -66 & -67.
Teresa counted 2 leaves on May 1st and 9 leaves on September 1st.
The difference in the number of leaves is:
9 - 2 = 7
Hence, the number of leaves has increased by 7 units.
