The skid marks for a car involved in an accident measured 54ft. Use the formula s=24d‾‾‾‾√ to find the speed, s, in feet per second, of the car before the brakes were applied.

For f(x)=2x+1 and g(x)= x^2 -7, find (f•g)(x)

Pick the expression that matches this description: a polynomial of the 5th degree with a leading coefficient of 7 and a constant term of 6 (choice a) 7x^5+2x^2+6 (choice b) 7x^6−6x^4+5 (choice c) 6x^7−x^5+5 (choice d) 6x^5+x^4+7
