Answer:
answer: b) x = 3, x = -1
Step-by-step explanation:
3|2x - 2| + 6 = 18.
divid by 3 :
|2x - 2| + 2 = 6
add -2 : |2x - 2| = 4
2x-2=4 or 2x-2=-4
2x=6 or 2x=-2
x=3 or x=-1
Answer:
Yes
Step-by-step explanation:
If the longest side squared is equal to the sum of the squares on the other 2 sides then they form a right triangle
longest side = 7.5
7.5² = 56.25
2.1² + 7.2² = 4.41 + 51.84 = 56.25
Thus the 3 values form a right triangle.
