Answer: 1- a square has 4 equal sides so if one side is 9cm then the rest are 9cm, so 9x4= 36cm
2- do the same thing as part 1 but add a power of 2 to it, so 36^2 = 1296cm
Step-by-step explanation:
-2.8, -2.6, -2.3

Answer:
a) M(-1, 4.5)
b) 10.63
c) 7/8
Step-by-step explanation:
a)
x = (3 + (-5))/2 = -1
y = (8 + 1)/2 = 4.5
M(-1, 4.5)
b) d = sqrt[(x1-x2)^2 + (y1-y2)^2] = sqrt(113) = 10.63
c) m = (y2-y1)/(x2-x1) = 7/8
Answer:
50
Step-by-step explanation:
