Area of a rectangle is length by width, width is x, length is x+8
x×(x+8)=240
x²+8x=240
x²+8x-240=0
Use the quadratic formula to solve
![x=\frac{-b±\sqrt{b^{2}-4ac}}{2a} x=\frac{-8±\sqrt{8^{2}-4(1)(-240)}}{2(1)} x=\frac{-8±\sqrt{64-4(-240)}}{2}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B-b%C2%B1%5Csqrt%7Bb%5E%7B2%7D-4ac%7D%7D%7B2a%7D%0Ax%3D%5Cfrac%7B-8%C2%B1%5Csqrt%7B8%5E%7B2%7D-4%281%29%28-240%29%7D%7D%7B2%281%29%7D%0Ax%3D%5Cfrac%7B-8%C2%B1%5Csqrt%7B64-4%28-240%29%7D%7D%7B2%7D%20)
![x=\frac{-8±\sqrt{1024}}{2} x=\frac{-8±32}{2} x=\frac{24}{2} OR \frac{-40}{2} x=12 OR -20](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B-8%C2%B1%5Csqrt%7B1024%7D%7D%7B2%7D%0Ax%3D%5Cfrac%7B-8%C2%B132%7D%7B2%7D%0Ax%3D%5Cfrac%7B24%7D%7B2%7D%20OR%20%5Cfrac%7B-40%7D%7B2%7D%0Ax%3D12%20OR%20-20)
It is a distance so can't be negative, so the answer must be 12
10 - 6v = -104 add 10 on both sides which is going to be -6v = -104 then you divide -6 on both sides and v = 17.3
Corn Grits : Water
1/4 : 1/2
1/4 x 4 : 1/2 x 4
1 : 2
3/2 : 2 x 3/2
1 1/2 : 3
So he will need 3 cup of water if he uses 1 1/2 cup of corns grits.
