Answer:
2x + 2
Step-by-step explanation:
6(x - 3) - 4(x - 5)
6*x - 6*3 - 4*x - 4 * -5
6x - 18 - 4x + 20
2x + 2
The answer is B. If -0.8 was below the other number, the other number would be above it.
A triangle is rotated around N to give the primed version.
A. Same shape and size -- TRUE. Rotation doesn't change shape or size.
B. Corresponding points are equidistant to N. That's TRUE, each point is rotated around N to get its corresponding point, which will be the same distance from N.
C. DN=D'N. TRUE, just an example of corresponding points.
D. Corresponding side lengths unequal, FALSE. Rotation doesn't change lengths.

- [Right Triangle Only] sin∅ = opposite over hypotenuse
Step-by-step explanation:
<u>Step 1: Define</u>
We have a right triangle. We can use trig to find the angle.
<u>Step 2: Identify Variables</u>
Angle = <em>x</em>
Opposite = 15
Hypotenuse = 23
<u>Step 3: Find Angle </u><em><u>x</u></em>
- Substitute: sinx° = 15/23
- Inverse: x° = sin⁻¹(15/23)
- Evaluate: x = 40.7057°
