<h3>
Answer: C) 2.6</h3>
Work Shown:
a = x, b = 3, c = 4
a^2 + b^2 = c^2 ... pythagorean theorem
x^2 + (3)^2 = (4)^2
x^2 + 9 = 16
x^2 = 16 - 9
x^2 = 7
x = sqrt(7)
x = 2.64575131106459
x = 2.6
Answer:
12\sqrt{14}x^2 (see photo)

What are the answer that’s they give
Answer:
The coordinates of point P are (1, -1)
Step-by-step explanation:
- If the point (x, y) reflected about the x-axis, then its image is (x, -y)
- To find the image of a point reflected about the x-axis change the sign of its y-coordinate
- The rule is R x-axis → (x, -y)
- If the point (x, y) reflected about the y-axis, then its image is (-x, y)
- To find the image of a point reflected about the y-axis change the sign of its x-coordinate
- The rule is R y-axis → (-x, y)
→ Assume that the coordinates of point P are (x, y)
∵ The coordinates of point P are (x, y)
∵ The rule of the reflection is R y-axis (P)
∴ Its image = (-x, y)
∵ The image = (-1, -1)
→ Equate the two images
∴ (-x, y) = (-1, -1)
∴ -x = -1
→ Divide both sides by -1
∴ x = 1
∵ y = -1
∴ The coordinates of point P are (1, -1)
