10(6+2z)+8 distribute 10
60+20z+8 add like terms
68+20z is answer since you can’t simplify anything further
Answer:
C) I and III only
Step-by-step explanation:
Let full pool is denoted by O
Days Hose x takes to fill pool O = a
Pool filled in one day x = O/a
Days Hose y takes to fill pool O = b
Pool filled in one day y = O/b
Days Hose z takes to fill pool O = c
Pool filled in one day z = O/c
It is given that
a>b>c

Days if if x+y+z fill the pool together = d
1 day if x+y+z fill the pool together 
I) d < c
d are days when hose x, y, z are used together where as c are days when only z is used so number of days when three hoses are used together must be less than c when only z hose is used. So d < c
III) 
Using (1)

Similarly

So,

Um
Answer:4√(13)
Step-by-step explanation:
Adjacent=12
Opposite=8
Hypotenuse=√((adjacent)^2+(opposite)^2)
hypotenuse=√(12^2+8^2)
Hypotenuse=√(12x12+8x8)
Hypotenuse=√(144+64)
Hypotenuse=√(208)
Hypotenuse=√(16x13)
hypotenuse=√(16) x √(13)
Hypotenuse=4 x √(13)
Hypotenuse=4√(13)
Answer:
24 degrees
Step-by-step explanation:
The sum of the exterior angles of a triangle is 360 degrees
2x + 6x + 7x = 360
15x = 360
x = 24
