1 answer:
Answer: x < 18
Step-by-step explanation:
x - 2 < 16
We eliminate 2 to isolate the variable, x by adding 2 to both sides. -2 + 2 = 0.
x < 18
We can test this because 17 is less than 18. Pretend x = 17
17 < 18✅
Mason subtracted 2, instead of adding 2.
In order to graph this, put an open circle at 18, and the arrow should point to the left.

Step-by-step explanation:
Area for rectangle is A=b×h
You can only multiply radicals with other radicals so... √17×√68= √1156
Simplify radical
√1156= 34
Then add 9
34+9= 43
