= 6√(80x^7) - 2x √(40x^5)
= 24x^3√(5x) - 4x^3√(10x)
Answer
B. 24x^3√(5x) - 4x^3√(10x)
12x + 16 x 2 because you get the same answer in the end
It should be 42/41 is the closest
Answer: 10 km/ hr
Step-by-step explanation:
In the graph below, Diego's speed at various points during his 10 kilometer race is shown on the y axis while the distance is shown on the x axis.
