(-4, 2), (-1, 2), and (-4, 0
Hello,
Answer D -3<x<27
Indeed:
1)
if x-12≥0 then x≥12 and
|x-12|=x-12x-12<15 → x<27
so 12≤x<27
2) if x-12<0 then
x<12 and|x-12|=-(x-12)<15
-x+12<15-x<3 → x>-3
So -3<x<12
Thus -3<x<12 U 12≤x<27 ⇔ -3<x<27
Answer:
the correct answer is 94 square cm
Step-by-step explanation:
You take (8x - 6) then add 80 =90 then solve for x
8x-6+80 =90
x= 2
The answer is 8,000 because 19 times 421 equals 7,888 and that estimated is 8,000
