I will give brainliest to whoever can answer this, I can’t figure out how I’m supposed to use Pascal’s Triangle to find my answer, I’ve been trying for hours, please help. Write out the coefficient of x^3 in the expansion of: (6-2x)^7

If f(x)=-x^2+6x-1 and g(x)=3x^2-4x-1,find(f+g)(x)

Show your workcan a right triangle have this sides? *how to prove it without using the pythagorean theorema*

Someone answer asap for ! the boiling point of water at an elevation of 0 feet is 212 degrees fahrenheit (°f). for every 1,000 feet of increase in elevation, the boiling point of water decreases by about 2°f. which of the following represents this relationship if b is the boiling point of water at an elevation of e thousand feet? a. e = 2b - 212 b. b = 2e - 212 c. e = -2b + 212 d. b = -2e + 212
