Answer:
18
Step-by-step explanation:
Given
x - 1 = 2 ( add 1 to both sides )
x = 3
Then
2x² = 2(3)² = 2 × 9 = 18
Answer:
D: {0≤x≤20}
R: {0≤y≤200}
Step-by-step explanation:
Domain and range are the possible values of x and y, respectively. For continuous graphs in set notation, inequalities can be used to represent the x and y values. As seen on the graph, the lowest possible x value is 0 and the highest is 20. All of the other values in between are also included. So the inequality 0≤x≤20 expresses all of the values. Additionally, because the circles are closed, the limit values, 0 and 20, are included. Next, the range is found in the same way. The lowest y is 0 and the highest is 200, with the limits included. So, the range inequality is 0≤y≤200.
The answer would be <u>16</u>. Neither 24, 28, or 36 can multiply by a whole number to equal 64, and 16 cannot be multiplied by a whole number to equal those values.

Answer: you subtract numbers?
Step-by-step explanation: i'm sorry, is that the whole question?
First it would be 42/6 and 48/6
So the first flag would be 7 feet and the second would be 8 feet long
