They’ve already earned $105 so they need $45 more to reach their goal
the correct question is
What values of b satisfy 3(2b+3)^2 = 36
we have
![3(2b+3)^2 = 36](https://tex.z-dn.net/?f=%203%282b%2B3%29%5E2%20%3D%2036%20)
Divide both sides by ![3](https://tex.z-dn.net/?f=%203%20)
![(2b+3)^2 = 12](https://tex.z-dn.net/?f=%20%282b%2B3%29%5E2%20%3D%2012%20)
take the square root of both sides
![( 2b+3)} =(+ /-) \sqrt{12} \\ 2b=(+ /-) \sqrt{12}-3](https://tex.z-dn.net/?f=%20%28%202b%2B3%29%7D%20%3D%28%2B%20%2F-%29%20%5Csqrt%7B12%7D%20%5C%5C%202b%3D%28%2B%20%2F-%29%20%5Csqrt%7B12%7D-3%20)
![b1=\frac{\sqrt{12}}{2} -\frac{3}{2}](https://tex.z-dn.net/?f=%20b1%3D%5Cfrac%7B%5Csqrt%7B12%7D%7D%7B2%7D%20-%5Cfrac%7B3%7D%7B2%7D%20%20)
![b1=\sqrt{3} -\frac{3}{2}](https://tex.z-dn.net/?f=%20b1%3D%5Csqrt%7B3%7D%20-%5Cfrac%7B3%7D%7B2%7D%20%20)
![b2=\frac{-\sqrt{12}}{2} -\frac{3}{2}](https://tex.z-dn.net/?f=%20b2%3D%5Cfrac%7B-%5Csqrt%7B12%7D%7D%7B2%7D%20-%5Cfrac%7B3%7D%7B2%7D%20%20)
![b2=-\sqrt{3} -\frac{3}{2}](https://tex.z-dn.net/?f=%20b2%3D-%5Csqrt%7B3%7D%20-%5Cfrac%7B3%7D%7B2%7D%20%20)
therefore
the answer is
the values of b are
![b1=\sqrt{3} -\frac{3}{2}](https://tex.z-dn.net/?f=%20b1%3D%5Csqrt%7B3%7D%20-%5Cfrac%7B3%7D%7B2%7D%20%20)
![b2=-\sqrt{3} -\frac{3}{2}](https://tex.z-dn.net/?f=%20b2%3D-%5Csqrt%7B3%7D%20-%5Cfrac%7B3%7D%7B2%7D%20%20)
Volume of a cone = (1/3) x Area of the base (B) x height(h)
V = (1/3)·420·180
= 25200 mm³
