the first one that is x-99....... goes to the second answer box
the second that is x-51......... goes to the first answer box
the third that is 150+x......... goes to the fourth answer box
the fourth that is 69-x......... goes to the third answer box
0=4(x²+8x+16)-12
0=4x²+32x+64-12
0=4x²+32x+52
0=x²+8x+13
D=b²-4ac
D=64-52=12
x=(-b-√D)/2a
x=(-b+√D)/2a
x=(-8-2√3)/2= (-2(4+√3))/2= -(4+√3)
AND
x=(-8+2√3)/2=-2(4-√3)/2= -(4-√3)
Answer:
It would be C
Step-by-step explanation:
since the whole area of the circle is 18 and the sector takes up one-fourth of the circle you would just divide 18 by 4 to get 4.5
Answer:
x = 5
Step-by-step explanation:
Comment
BD is already given to you as bisected. AC must also be bisected. That means that 6x and 7x - 5 must the the same value. Then and only then will the figure be a parallelogram. (a four sided figure is a parallelogram if the 2 diagonals are bisected.
Equation
6x = 7x - 5 Subtract 6x from both sides
Solution
6x - 6x = 7x - 6x - 5 Simplify
0 = x - 5 Add 5 to both sides
5 = x - 5 + 5 Simplify
x = 5
