<span>here we can use Pythogoras' theorem.
in right angled triangles the square of the hypotenuse is equal to the sum of the squares of the other 2 sides.
hypotenuse is 19 cm. One side is 13 cm and we need to find the length of the third side.
19</span>²<span> = 13</span>²<span> + X</span>²<span>
X - length of the third side
361 = 169 + X</span>²<span>
X</span>²<span> = 361 - 169
X</span>²<span> = 192
X = 13.85 the length of third side rounded off to the nearest tenth is 13.9 cm</span>
Answer:
(x + 1)² = (2x)²
(1 + 1)² = (2(1))²
2² = 2²
4 = 4
(-1 + 1)² = (2(-13))²
(-12)² = (-26)²
Not true
x = -13 satisfies neither
Rise over run = y2 - y1 / x2 - x1
3-12/-8 - (-17)
-9/ 9 which simplifies to —> -1 = slope
Answer:
Rise = 15.
Run = 1.
Step-by-step explanation:
Hope this helps!

First take 10,000 * 2 = 20,000, because each of the 10,000 tickets cost 2 dollars.
3000(1/20000) + 1000(3/20000) + 500(5/20000) + 100(20/10000) = 10500/20000 = .525
Thus, each ticket is worth 52.5 cents.
Hope it helps <3
