Answer:
2(5) = <u><em>10 feet</em></u>
Step-by-step explanation:
1) 4.6x + 5x + 6x + 2x = 17.6x
2) 17.6x = 88
<u><em>x = 5</em></u>
Plug 5 for x in 2x.
<u><em>2(5) = 10. </em></u>

Answer:
![a_n=9(4^{n-1})](https://tex.z-dn.net/?f=a_n%3D9%284%5E%7Bn-1%7D%29)
Step-by-step explanation:
we know that
In a <u>Geometric Sequence</u> each term is found by multiplying the previous term by a constant, called the common ratio (r)
In this problem we have
![a_2=36\\ a_5=2,304](https://tex.z-dn.net/?f=a_2%3D36%5C%5C%20a_5%3D2%2C304)
Remember that
----->
-----> equation A
Substitute the values of a_5 and a_2 and solve for r
Find the value of a_1 in equation A
![36=a_1(4)](https://tex.z-dn.net/?f=36%3Da_1%284%29)
![a_1=9](https://tex.z-dn.net/?f=a_1%3D9)
therefore
The explicit rule for the nth term is
![a_n=a_1(r^{n-1})](https://tex.z-dn.net/?f=a_n%3Da_1%28r%5E%7Bn-1%7D%29)
substitute
![a_n=9(4^{n-1})](https://tex.z-dn.net/?f=a_n%3D9%284%5E%7Bn-1%7D%29)
Which expression?? Can u please post it I wanna help!
Answer:
i think b,e,f,
Step-by-step explanation:
we can subtract the trapezium (white part) formed after from the trapezium (including white and grey) to get area of striped part
area of trapezium is
where $a$ and $b$ are parallel sides.
for bigger trapezium, $h=4$ parallel sides are $5$ and $5$
hence area is $\frac{4(5+5)}{2}=20$
similarily area of white trapezium, $\frac{4(3+3)}{2}=12$
and area of striped part is $20-12=8$
