Answer:
65
Step-by-step explanation:
150-(4^2+4)/2
150-(16+4)/2
150-(20)/2
130/2=65
140
P: parenthesis
E: exponents
M: multiply
D: Division
A: add
S: subtract
150-(4^2+4)/2 exponent first 4^2= 4*4=16 you do this because it is
inside the parenthesis
150-(16+4)/2 you still have parenthesis so solve that next
150-20/2 next you divide because there is no multiplication
150-10 then subtract because there is no addition
140 is your final answer
-4, -3, -2, -1, 0, 1, and 2

Applying Pythagoras' Theorem,
(BD)^2= (CD)^2 + (BC)^2
(BC)^2= 65^2 - 60^2
(BC)^2= 625
BC= √625= 25
