Answer:
39 cm
Step-by-step explanation:
using the x component go find 12 cm width and follow the line up until it intersects the graph. then follow that point left to estimate the height at that point to estimate 37.5 but more accurately you can use the given equation y=3.25x and plug in your x of 12 to get y=39

Answer:
if we take the total cost of the grapes, and divide by the number of pounds of grapes we can conclude that each pound of grapes costs $3. so 5 pounds of grapes multiplied by $3 per pound, gives us $15 for 5 pounds of grapes.
B. (k+10f)(k-5f) you can tell in 2 ways. 1. if the second sign is neg then the signs in the factors are going to be one neg and one positive so that knocks out C and D. Then you look at the second term and since the 5 is positive then the 10 has to be positive so you end up with a positive 5kf.
The second way is to FOIL them out. When you check B you get
![k^{2} -5kf+10kf- 50f^{2}](https://tex.z-dn.net/?f=%20k%5E%7B2%7D%20-5kf%2B10kf-%2050f%5E%7B2%7D%20)
combine your like terms and you have your original expression of
![k^{2} +5kf-50 f^{2}](https://tex.z-dn.net/?f=%20k%5E%7B2%7D%20%2B5kf-50%20f%5E%7B2%7D%20)
Hope that helps
