Answer:
Average speed is calculated by dividing distance by time (e.g. miles/hour). Okay we're going to talk about average speed, instantaneous speed is the distance that you're covering at a specific time. So 100 kilometers an hour, average speed is the total distance you're going to cover over a period of time.
If x = 8, then the factor is (x - 8); likewise, if x = -5, then the factor is (x + 5). FOIL those together and get B
Answer:
16,000,000
Step-by-step explanation:
to start off your going to need to use PEMDAS (parenthesis exponents multiplication division addition subtraction)
so we are going to start IN the parenthesis the next step is doing the exponents so its going to look like this 1,000,000
rewrite the problem: 4(4×1,000,000)
use the next step in PEMDAS multiplication rewrite the problem:
4(4,000,000)
multiply: 16,000,000
Find the area of the rectangle. You can find the area of a rectangle with the following formula:
![A = wl](https://tex.z-dn.net/?f=A%20%3D%20wl)
w = width, and l = length.
Plug in your width and length:
![20 * 10 = 200](https://tex.z-dn.net/?f=20%20%2A%2010%20%3D%20200)
The area of the rectangle is 200 square centimeters.
The area of a square is also given by width * length. Multiply the sides together:
![2x * 2x = 4x^{2}](https://tex.z-dn.net/?f=2x%20%2A%202x%20%3D%204x%5E%7B2%7D)
The area of a square is 4x^2.
Because you're cutting away the square from the rectangle, you will subtract the area of the square from the area of the rectangle. The following equation will be your answer:
6) subtract 16 on both sides
then it should be x/4>18
then you would times 18 by 4 and get
c as the answer
7) the answer is d.
because 52-12 is 40 and 52/4 is 13
