An equation is shown. 2(a+b)=c solve the equation for b in terms of a and c. explain your answer. a. b=c−2−a; subtract both 2 and a from each side. b. b=c−2a; distribute 2 to get 2a+b, then subtract 2a from each side. c. b=c+2a/2 ; distribute 2 to get 2a+2b, add 2a, then divide by 2. d. b = c−2a/2 ; distribute 2 to get 2a+2b, subtract 2a, then divide by 2.

Lindsay is creating a bridge out of dried pasta and glue. in her plans, she sketches the graph to determine the lengths of the noodles, in centimeters, needed for the arch to increase the length of the bridge in 1 centimeter increments.which function did lindsay use to create her design? f(x) = (x – 5)2 + 8 f(x) = –(x + 5)2 + 8 f(x) = 0.5(x + 5)2 + 8 f(x) = –0.5(x – 5)2 + 8
