40.55 * 6 = 243.3
= $243.30
recall in a perfect square trinomial, the middle term is the tale-tell guy, we know the middle term is the product of 2 and the two other guys without the exponent, so in this case 6x = 2*√x² * √c.
![\bf 6x=2\cdot \sqrt{x^2}\cdot \sqrt{c}\implies 6x=2\sqrt{x^2c}\implies 6x=2x\sqrt{c}\\\\\\\cfrac{6x}{2x}=\sqrt{c}\implies 3=\sqrt{c}\implies 3^2=c\implies 9=c](https://tex.z-dn.net/?f=%20%5Cbf%206x%3D2%5Ccdot%20%5Csqrt%7Bx%5E2%7D%5Ccdot%20%5Csqrt%7Bc%7D%5Cimplies%206x%3D2%5Csqrt%7Bx%5E2c%7D%5Cimplies%206x%3D2x%5Csqrt%7Bc%7D%5C%5C%5C%5C%5C%5C%5Ccfrac%7B6x%7D%7B2x%7D%3D%5Csqrt%7Bc%7D%5Cimplies%203%3D%5Csqrt%7Bc%7D%5Cimplies%203%5E2%3Dc%5Cimplies%209%3Dc%20)
