Step-by-step explanation:
3x - 10 < 2
3x < 2 + 10
3x < 12 Divide through by 3.
x < 12/3
x < 4
The next number is 5.
Each number in the sequence is the (positive) difference of the previous two numbers.
Answer:
disagree
Step-by-step explanation:
If the triangle is right, then the square of the longest side must equal the sum of the squares on the other 2 sides.
longest side = 12 ⇒ 12² = 144
7² + 7² = 49 + 49 = 98
Since 144 ≠ 98 then triangle is not right
