Answer:
A; C; 35; A; A,B,D
Step-by-step explanation:
1. GH = sqrt(4^2 + 6^2) = sqrt(52) = 2sqrt(13)
FG = sqrt (9^2 + 4^2) = sqrt97
Add them together, and multiply by 2 to get the perimeter (because JH = GH, and FG = FJ). You get A (4sqrt13 + 2sqrt97)
2. C, because that is basically saying that all the angles are right
3. The lines are equally spaced (horizontally), and parallel, making them increase by the same amount between each. This means that (8x-7) - (7x+2) = (7x+2) - (10x-1).
Simplify:
x-9 = -3x+3 -->
4x = 12,
x =3
This means that the parallel lines' lengths are 17, 23, 29. This means that they increase by 6. This makes the longest base 29 + 6 = 35
4. The sum of exterior angles is ALWAYS 360. Divide 360 by 18 to find out how many sides it has. 360/18 = 20. The answer is A.
5. A, B, D (Laws of Rhombuses)
Answer:
Consider a circle centered at C(-2,-4). If the point P(1,-1) lies on the circle, then which of the following points also lies on the circle?
<h3>A. (-2, -√18)</h3>
B. (-2+√18, -4)
C. (√18, -4)
D. (-2, 4+√18)
Step-by-step explanation:
- If the distance is greater than the radius, the point lies outside. If it's equal to the radius, the point lies on the circle. And if it's less than the radius, you guessed it right, the point will lie inside the circle.
hope it's help you

<span>A regular hexagon is defined as a hexagon that is both equilateral and equiangular. It is bicentric, meaning that it is both cyclic (has a circumscribed circle) and tangential (has an inscribed circle).
The common length of the sides equals the radius of the circumscribed circle, which equals {\displaystyle {\tfrac {2}{\sqrt {3}}}} {\displaystyle {\tfrac {2}{\sqrt {3}}}} times the apothem (radius of the inscribed circle). All internal angles are 120 degrees. A regular hexagon has 6 rotational symmetries (rotational symmetry of order six) and 6 reflection symmetries (six lines of symmetry</span>
Answer:
2 inches in the drawing
Step-by-step explanation:
Because if 5 feet equals 1 inch and 5 times 2 equals 10 feet (so now we do the same to the other side) 1 times 2 and that equals to 2 inches.
