Answer: 13.4 meters by 6.1 meters
Step-by-step explanation: Applying the scale to the given measurements gives us: 13.4 meters long and 6.1 meters wide
Answer:
Step-by-step explanation:
I think it is A
Perimeter is the boundary/outline/ surrounding
For example if you measure around your house that would be the perimeter.
Area is the size of something.
Like if you wanted to know the amount of space in a box.
Answer:
x = 30
since 3x = 90 degrees, then x = 90/3 = 30
Step-by-step explanation:
Answer:
C and D
Step-by-step explanation:
Equating the line A and the parabola, we get
-3x + 2 = x² - 3x + 4
0 = x² - 3x + 4 +3x - 2
0 = x² + 2
-2 = x²
which has no real solutions. Then, the line A and the parabola don't intersect each other.
Equating the line B and the parabola, we get
-3x + 3 = x² - 3x + 4
0 = x² - 3x + 4 + 3x - 3
0 = x² + 1
-1 = x²
which has no real solutions. Then, the line B and the parabola don't intersect each other.
Equating the line C and the parabola, we get
-3x + 5 = x² - 3x + 4
0 = x² - 3x + 4 + 3x - 5
0 = x² - 1
1 = x²
√1 = x
which has 2 solutions, x = 1 and x = -1. Then, the line C and the parabola intersect each other.
Equating the line D and the parabola, we get
-3x + 6 = x² - 3x + 4
0 = x² - 3x + 4 + 3x - 6
0 = x² - 2
2 = x²
√2 = x
which has 2 solutions, x ≈ 1.41 and x ≈ -1.41. Then, the line D and the parabola intersect each other.
