So Camille is 10 Donny is 6and tommy is 8
Starting at 4 count to the left, there's 5 zero
so answer
<span>0.000041 = 4.1 x 10^-5</span>
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)
For this one, to remove the 9 from the left you must multiply it on both sides; the answer is C. (The answer always has the opposite operation than the one used in the problem. The opposite of multiplication is division and the opposite of addition is subtraction.)
