Answer:
64
Step-by-step explanation:
this is the sequence of cube. ... hence the sequence will be 1-8-27-64-125-216.
(wen 64 is already tere)
Answer:
x = 10, y = 10
Step-by-step explanation:
Using the sine/ cosine ratios in the right triangle and the exact values
sin60° = , cos60° = , then
sin60° = = = ( cross- multiply )
2x = 20 ( divide both sides by 2 )
x = 10
and
cos60° = = = ( cross- multiply )
2y = 20 ( divide both sides by 2 )
y = 10
Answer:
None of these!
Step-by-step explanation:
x + y + z = x + y + z only over here
Answer:
B 6 centimeters
Step-by-step explanation:
y = x + 2
2x + 3y = 36
substitute y = x+2 into the second equation
2x + 3 (x+2) = 36
distribute
2x + 3x+ 3*2 = 36
combine like terms
5x+6 = 36
subtract 6 from each side
5x +6-6 = 36 -6
5x = 30
divide by 5
5x/5 = 30/5
x = 6
the short side is x =6
the longer side is
y= x+2
y = 6+2
y =8
Step-by-step explanation:
I think it's 8 down again.
And 7 down.
8•7 = 56
