To find the answer for x, you have to use the pythagoryen theorem. The line AC is 16 inches, but the little segment of the triangle is 4 inches. So first, you have to use the pythaoryen theorem and get this equation: CB plus AB=16 inches. Once you find CB, use it again to find the value of DB. DB plus DC equals CB. Then DB = X.
Answer:

subtract the x from the other x and the y from the other y. Put that equation in a square root.
Answer:
A
Step-by-step explanation:
S=weight of soybean protein, C=weight of cornmeal protein.
Total weight of each protein is 0.18S+0.19C=0.17×360=61.2 lb.
Total weight of meal is S+C=360 lb. So S=360-C.
Therefore 0.18(360-C)+0.19C=61.2, 64.8-0.18C+0.19C=61.2, 0.01C=-3.6.
Clearly we would get a negative value for C. When you look at the question you will realise that there is a larger percentage of protein in the ingredients than there is in the mixture. The expected amount of protein in the mixture should be between 18% and 19%. Please check your figures.
