Answer:
Step-by-step explanation:
y= 3 (-4)+5
y= - 12+5
y= -7
Answer:
-6
Step-by-step explanation:
Are you sure that z + 2+ z is correct? x and y do not appear here.
z + 2+ z simplifies to 2z + 2, and so, if z = -4, z + 2+ z has the value
2(-4) + 2, or -6.
Answer:
Step-by-step explanation:
length = 120/8 = 15 feet
perimeter = (15 + 8) x 2 = 46 feet
Answer:
if it is thren true (???) you gots to be more specific...pls)
Step-by-step explanation:
is this a trues or false satement
Step-by-step explanation:
LHS=(1-sin60)/cos60
=(1-√3÷2)/1÷2
=2(1-√3÷2)
=2-√3
RHS=(1-tan30)/(1+tan30)
={1-(1÷√3)}/{1+(1÷√3)}
={(√3-1)/√3}/{(√3+1)/√3}
=(√3-1)/(√3+1)
={(√3-1)(√3-1)}/{(√3+1)(√3-1)}
=(3-√3-√3+1)/(3-1)
=(4-2√3)/2
=2-√3
Therefore LHS=RHS
