A rectangular garden has a perimeter of 320 feet. The length of the garden is 8 feet longer than the width. What is the width of the garden? (hint: substitution method)

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

What is the vertex form of f(x) = x2 + 6x + 3

If x is 6, then 7x= a. 13 b. 42 c. 42x d. 76
