Answer:
yes
Step-by-step explanation:
You can check to see if the numbers satisfy the Pythagorean theorem.
9² +12² ?= 15²
81 + 144 = 225 . . . . yes these segments form a right triangle
_____
You know that segments of lengths 3, 4, 5 form a right triangle. This is the first "Pythagorean triple" that most folks run across. The segments given here are all 3 times those numbers, so will also form a right triangle.
1. 80 ounces = 5 pounds and 8 pounds = 128 ounces so (8>80)
2. 3 pounds = 48 ounces and 50 ounces = 3.1 pounds so (3<50)

Answer:
For A:
Draw a number line with a dot on 3
For B:
Draw a number line connecting points at -3 and 10/3. Open dot an 10/3, and closed dot at -3
Intersection: x = 3
Step-by-step explanation:
A = {x : -8 < 5x + 2 = 17, x belongs to I}
-8 < 5x + 2 = 17
-10 < 5x = 15
-2 < x = 3
It's only x = 3
B = {x : -2 <= 7 + 3x < 17, x belongs to R}
-9《3x < 10
-3《x < 10/3
Since there's only one value in A and that also lies in B, the intersection is at x = 3
Answer:
D
Step-by-step explanation:
3(x-2)+2x=3x+2x-6=5x-6
