You are trying to find 15% of 72.50 so you would need to multiply your new decimal (.15) to your meal total. This will give you 10.875 or 10.88.
Answer:
2sqrt(2)
Step-by-step explanation:
5x^2 - 40 = 0
=> 5x^2 = 40
=> x^2 = 40/5 = 8
=> x = sqrt(8) = sqrt(4 x 2) = 2sqrt(2)
X axis ; 3
Y axis ; -3
Your answer ; 3, -3
