112/2=56 (sum of both lengths)
4x=56
x=14
length=42
width=14
He pays $780 for the television set.
1200*.35=420
1200-420=780
If the two triangles are congruent it means that their side lengths are equal, so we can assume that x = 3x - 8 and so 2x = 8 and x = 4. Hope that helps :)
Step-by-step explanation:
m-(-3)>17
m +3>17
m >17-3
m>14
75% because 9/12 simplified is 3/4 which is 75%
