Answer:
A(-4, 1)
Step-by-step explanation:
The parts being equal means ...
A - P = P - B
A = 2P - B . . . . . . . . useful to remember for P being the midpoint of AB
A = 2(-1, 4) -(2, 7) = (-2-2, 8-7)
A = (-4, 1)
Answer:
8 cm
Step-by-step explanation:
The maximum length of the string will be the greatest common divisor of 32 , 16 , 8
32 = 2 * 2 * 2 * 2 * 2
16 = 2 * 2 * 2 * 2
8 = 2 * 2 * 2
GCD = 2* 2 * 2 = 8
The maximum length of the string = 8 cm
