Plug in 3 for x so
2(3)+2
6+2=
8
The evaluation is 8
Answer:
x = 4
Step-by-step explanation:
since each side is equal to x + 1 and there are 6 sides, to get x alone, you have to subtract 1, six times from the perimeter.
1 × 6 = 6
30 - 6 = 24
then divide that by the number of sides (6)
24 ÷ 6 = 4
x = 4!
Answer:
(20,-4)
Step-by-step explanation:
We are given;
One end point as (2,5)
Point of division as (10,1)
The ratio of division as 4:5
We are required to calculate the other endpoint.
Assuming the other endpoint is (x,y)
Using the ratio theorem
If the unknown endpoint is the last point on the line segment;
Then;
![\left[\begin{array}{ccc}10\\1\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D10%5C%5C1%5Cend%7Barray%7D%5Cright%5D)
=![\frac{4}{5} \left[\begin{array}{ccc}x\\y\end{array}\right]](https://tex.z-dn.net/?f=%5Cfrac%7B4%7D%7B5%7D%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7Dx%5C%5Cy%5Cend%7Barray%7D%5Cright%5D)
+![\frac{5}{9}\left[\begin{array}{ccc}2\\5\end{array}\right]](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D%7B9%7D%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D2%5C%5C5%5Cend%7Barray%7D%5Cright%5D)
Therefore; solving the equation;
solving for x
x = 20
Also
solving for y
y= -4
Therefore,
the coordinates of the end point are (20,-4)
Answer:
1,000,000,000 leaves or 1 x 10^9 leaves
Step-by-step explanation:
One large oak tree has 2 x 10^5 leaves, so we can make that number to 200000
There are 5 x 10^3 oak trees in a forest, we can make that number to 5000
Since we want to find out how many leaves are in the whole forest we multiply: 200000 x 5000 = 1,000,000,000
So approximately there are 1 billion leaves or 1 x 10^9 leaves
