Answer:
rub the magnets with a stronger magnet then they would be more magnetized
Explanation: If you rub a magnet with lets say some metal then that metal would be magnetized so if you where to rub those 2 magnets with a stronger magnet those magnetized would be magnetized even more than they already are
150 x 5= 750
20 x 5= 100 ... so they should expect 100 cellphones to be defective
Answer:
step 1: move the -4 to the right: x^2 -2x = 4
step 2: add 1 to each side: x^2 -2x + 1 = 4 + 1
step 3: factor the left side and simplify the right side: (x-1)^2 = 5
step 4: take the square root of each side: x - 1 = sqr root of 5
step 5: move the 1 to the other side: 
and 
When a triangle is obtuse, the length of c^2 is bigger than the combined lengths of a^2 and b^2.
a^2+b^2<c^2
"A" is the best answer.
I hope this helps!
