8 0

Answer:

-4, -2, 0 or -8, -6, -4

Step-by-step explanation:

#1 =x

#2 = x+2

#3 = x+4

x(x+2) = -10(x+4) + 8

x^2 + 2x = -10x - 40 + 8

x^2 + 12x + 32 = 0

(x+8)(x+4) = 0

x = -8 or x = -4 so:

#1 = -8 or -4

#2 = -6 or -2

#3 = -4 or 0

$a+b+c=180, \text{ }c+e=180 \implies \\ a+b+c=c+e \implies \\ a+b=e\\$

This result is actually true for any exterior angle. The exterior angle of a triangle is equal to the sum of the two remote angles, and above is a short proof of it.

Allison was looking at a map with the following scale indicator. 2 inches = 6 miles

xeze [42]

answer: 9

the answer is 9 because 6 ÷ 2 = 3, and if you multiply 3 with 3, you get 9. you multiply the number 3 because you need to find out the distance in miles, and since in inches it is 3, you need to multiply by 3 because that is the formula to get miles.
