Answer:
x = 3/8 +/- i(√5)/8.
Step-by-step explanation:
I can't see any list by this is the solution of the equation:
x^2 - 3/4x = -1/4
x^2 - 3/4 x + 1/4 = 0
Multiply by 4 to remove the fractions:
4x^2 - 3x + 1 = 0
x = [-(-3) +/- sqrt(3)^2 - 4*4*1)] / 8
x = 3/8 +/-√ (-5) / 8
x = 3/8 +/- √5 i / 8
Answer:
tom = 166, ben = 581
Step-by-step explanation:
2 + 7 = 9
747 ÷ 9 = 83
therefore 1 part = 83
83 x 2 = 166
83 x 7 = 581
tom has 2 parts so he has 166
ben has 7 parts so he has 581
That would be true because the adjacent side to B is 4 and the hypotenuse is 5 and the formula for cos b is adjacent/hypotenuse
Hope this helps!
