Here is the set up:
x
x + 2
x + 4
x^2 + (x + 2) + (x + 4)^2 = 170
Take it from here.
Answer:
540
Step-by-step explanation:
Amount of antifreeze in the 90% solution + amount of antifreeze in the 20% solution = amount of antifreeze in the 80% solution
0.90 x + 0.20 (90) = 0.80 (x + 90)
0.90 x + 18 = 0.80 x + 72
0.10 x = 54
x = 540
You need 540 gallons of 90% antifreeze solution.
I’m pretty sure- B) counterclockwise rotation

Answer:
Step-by-step explanation:
R-value can range from -1 to 1 with correlation being strongest at -1 and 1 and weakest at 0.
So the answer is D. -0.9.
