Given f(x)=x2+3x and g(x)=2x2, find (f ∘ g)(−1).

Solve this equation using substitution. {4x + y = −2} {4x + 6y = 44}

Iam a rectangle. my perimeter is 60 feet. how much are do i cover?

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
