Hello,
Your sequence is arithmetic.
10.5-9=1.5
9-7.5=1.5
7.5-6=1.5
6-4.5=3
4.5-3=1.5
3-1.5=1.5
1.5-1.5=0
...
f(x)=f(n-1)-1.5 is the iterative rule.
f(1)=10.5
f(2)=10.5-1.5=9
f(3)=10.5-2*1.5=7.5
f(4)=10.5-3*1.5=6
...
f(n)=10.5-1.5*(n-1) is the general form.
The answer is 24 square units
Answer:
width=11/2
length=8
Step-by-step explanation:
44=(2w-3) x w <em>area for a rectangle (44) = the length (2w-3) times the width (w)</em>
44=2w^2 - 3w <em>distribute</em>
2w^2-3w-44 = 0 <em>subtract 44 from both sides</em>
(w+4)(2w-11) <em>factor</em>
width=11/2
(11/2 x 2) - 3
length = 8
1/3
2/5
Hope this helps :)
