Its 11/12 , you need to divide the "wanted results" (every dog which is either black, with spots or both ) by every every possible result ( all dogs ). so 11/12=0.92
Answer:
x=11
Step-by-step explanation:
(7x+14)=(9x-8)
7x-9x=-14-8
-2x=-22
-2x/-2=-22/-2
x=11
Pentagons have five sides, so 5x = 20. Only value for x that makes this true is 4, so 4 cm per side.
