4) -9
Explanation:
Arithmetic Sequence Formula
a(n) = a1 + (a - 1) (d)
a= term position
a(n)= nth term
a1= first term
Answer:
x = 3
Step-by-step explanation:
-14x+14=4x-40
−14x+14=4x−40
The equation for the area of a rhombus is
![A = \frac{ (d_1)( d_2)}{2}](https://tex.z-dn.net/?f=A%20%3D%20%20%5Cfrac%7B%20%28d_1%29%28%20d_2%29%7D%7B2%7D%20)
, where
![d_1](https://tex.z-dn.net/?f=d_1)
and
![d_2](https://tex.z-dn.net/?f=d_2)
are the length of the diagonals of the rhombus, and A = area of the rhombus.
Your two diagonals are:
![d_1](https://tex.z-dn.net/?f=d_1)
= 5m + 5m = 10m
![d_2](https://tex.z-dn.net/?f=d_2)
= 10m + 10m = 20m
Plug these values into the equation for the area of a rhombus:
![A = \frac{ (d_1)( d_2)}{2} \\ A = \frac{ (10)(20)}{2} \\ A = \frac{200}{2} \\ A = 100m^2](https://tex.z-dn.net/?f=A%20%3D%20%5Cfrac%7B%20%28d_1%29%28%20d_2%29%7D%7B2%7D%20%5C%5C%0AA%20%3D%20%5Cfrac%7B%20%2810%29%2820%29%7D%7B2%7D%20%5C%5C%0AA%20%3D%20%20%5Cfrac%7B200%7D%7B2%7D%20%5C%5C%0AA%20%3D%20100m%5E2)

Answer: 100
Answer: 315 ft
Step-by-step explanation: The length of a rectangle is length times width, so 21 (length) times 15(width) is 315 ft.
