2 triangular bases and three rectangular lateral faces
-x-5
- -5x^2 - 3
or
(-x-5) - (-5x^2 - 3)
First, distribute the -. So then it becomes
-x - 5 + 5x^2 + 3
Since you can't add 5x^2 to -x. You can only combine -5 and 3.
Thus it becomes
- x + 5x^2 -2
However, you order in exponents so
5x^2 - x - 2
would be the correct answer.
5 x 10^5 = 500,000
2 x 10^5 = 200,000
The scientific notation 5 x 10^5 is 2.5 times greater than the scientific notation of 2 x 10^5.
The first one, the fourth one, and the middle one
Answer:
660 mm
Step-by-step explanation:
we know that
The scale factor is 
That means
1 unit in the model represent 15 units in the actual
or
1 m in the model represent 15 m in the actual
To find out the height of the model rocket, divide the height of the actual rocket by 15
so

Convert m to mm
Remember that

To convert meters to millimeters, multiply by 1,000
so
