Answer:
3 - 3i
Step-by-step explanation:
I think you meant:
6
------------
1 + i
To simplify this, that is, to "rationalize the denominator," multiply both numerator and denominator by the conjugate of 1 + i, which is 1 - I:
6(1 - i)
----------- = 3(1 - i)= 3 - 3i
1 -(-1)
Answer:
Me
Step-by-step explanation:
Answer:
GH=12
Step-by-step explanation:
Definition of a perpendicular Bisector: a perpendicular bisector intersects another line segment at 90° and divides it into two equal parts.
Therefore it divides the line GI into two equal parts. That means that GH=HI and it was given that HI=12.
Answer:
2x + 4y = 4
-8x + 8y = -16.
Step-by-step explanation:
We can find an equivalent system by multiply the 2 equations by 2.
x + 2y = 2 multiplied by 2 is 2x + 4y = 4.
Answer:
48, 54 and 60
Step-by-step explanation:
Let the three multiples be 6x, 6(x+1) and 6(x+2) respectively.
6x+6(x+1)+6(x+2)=162
6x+6x+6+6x+12=162
18x=144
x=8
Therefore, the three multiples are 6(8), 6(8+1) and 6(8+2)
i.e. 48, 54 and 60
