Determine the length of the openings of the pipe
To do this, we simply add 40mm to the length of the pipe.
This gives:
<em>Hence, the opening must be 128mm</em>
Pythagoras' Theorem only works with right angle triangles.
A makes a right angles triangle because:
√3² + 4² = 5
However B doesn't because:
√7² + 8² = 10.631 (which is not 9)
Nor does C because:
√3² + 9² = √90 (which is not √95)
So the answer is A
Answer:
y=11/2
Step-by-step explanation:
6y+11=3y+5y
11=3y+5y-6y
11=2y
11/2=y
The answer of the factored polynomial is
(X+2)(2x+1)
