Hello from MrBillDoesMath!
Answer:
1 - i sqrt(11) , 1 + i sqrt(11)
Discussion:
Translating the Question into mathematical symbols:
x * y = 12 (*)
x + y = 2 (**)
From (**), y = 2 - x. Substitute this value in (*)
x * y = x * (2-x) = 12 =>
2x - x^2 = 12 => add x^2, subtract 2x from both sides
0 = x^2 -2x + 12
Solving using the quadratic formula gives
x = 1 - i sqrt(11)
and
y = 1 + i sqrt(11)
Thank you,
MrB
Find the area of all six rectangular faces of the prism. (A= l x b)
A1: 3.1 x 5 = 15.5
A2: 7.4 x 3.1 = 22.94
A3: 5 x 7.4 = 37
A4: 3.1 x 7.4 = 22.94
A5: 7.4 x 5 = 37
A6: 3.1 x 5 = 15.5
Add all answers together to get your answer of 150.88 cm^2.
Hope this helps!!
Answer: -3 and -11
Step-by-step explanation: The only factors of 33 are 1, 3, 11, 33. 3 and 11 are the best canidates because 33 and 1 added together gives you 34. -11 and -3 added is -14
so it'd be the first, third and fourth one. all you gotta do is draw a vertical line through the middle of the 1st, 3rd and 4th.
Answer:
1/2
Step-by-step explanation:
=-x2+4X-3
3= -x2+4x
3/2=3x
3=3x×2
3/3=2x
x=1/2
