So if we want to know the common solution(s) to a system of 2 equations, So we can just set both equations equal to each other and solve for the x value(s). That’s where I start below;
2x^2-13x+21 = 2x^2+9x-56
2x^2 cancels out and moving everything to one side and anything with an x variable to the other side we have then;
-22x=-77
22x=77 by cancelling the negative signs
x=77/22 therefore x=7/2 or 3.5
Hope this helps you. Any questions please ask.

B) 66 pounds of beef needed .25*264
C) 66 pounds
Answer:
![{4}^{3} = 64](https://tex.z-dn.net/?f=%20%7B4%7D%5E%7B3%7D%20%20%3D%2064)
Step-by-step explanation:
![\frac{ {4}^{8} }{ {4}^{5} } = {4}^{3}](https://tex.z-dn.net/?f=%20%5Cfrac%7B%20%7B4%7D%5E%7B8%7D%20%7D%7B%20%7B4%7D%5E%7B5%7D%20%7D%20%20%3D%20%20%7B4%7D%5E%7B3%7D%20)
Subtract the numerator exponent from the denominator exponent.
![8 - 5](https://tex.z-dn.net/?f=8%20-%205)
We see here in the diagram that the base is a. We know this because the height is perpendicular to it. We also know the height is bsin(C) which, when replace h for bsin(C) and a for the base, we get A=absin(C), which is the second option.
