Answer:
The hypotenuse is 17
Step-by-step explanation:
We can use the Pythagorean theorem since this is a right triangle
a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse
8^2 + 15^2 = c^2
64 + 225 = c^2
289 = c^2
Take the square root of each side
sqrt(289) = sqrt(c^2)
17 = c
Number 5 is x = 18 and number 6 is x = -2

Answer:
x=0
Step-by-step explanation:
y=-5x -6
10x + 2y = -12
Substitute y into the equation:
10x+2(5x-6)=-12
Use distributive property
10x+10x-12=-12
Add like terms
20x-12=-12
Add 12 to both sides of the equation
20x=0
divide each side by 0
x=0
