If y = 5x^3 − 10x, determine [dy/dt] when x = 0 and [dx/dt] = −2 . help please ;)

1)Suppose Q = x^3 y^2 . If [dQ/dt] = −1 and [dx/dt] = 2, find [dy/dt] when x = 4 and y = 5 . [dy/dt] =______ 2)Let A be the area of a circle with radius r. If [ dr / dt ] = 2, find [ dA / dt ] when r = 3

i don't get it.. dq/dt isnt it 3x^2y and i don't get the part where you put 3y^2x^2 how many exponents are there

I dont know so why wont you tell us the answer

I'm. Stupid and i have a D in math class so please help me. I in 8th grade in a double. Block pre algebra and in intensive math class. So please help im trying to get a good grade so i can graduate in High school
