Answer:
x^2+9x+14
Step-by-step explanation:
x×(x+7)+2×(x+7)
x^2+7x+2x +14
x^2+9x+14
We need to be able to see the graph in order to be able to know for sure, but most likely D) Point E.
Represent the length and width by L and W. Then L = W + 4.
Using the perimeter formula: P = 2L + 2W = 68 ft = 2W) + 2(W+4).
Solve for W: 68 = 2W + 2W + 8, or 4W = 60. Thus, W = 15 and L = 19.
The dimensions of the rectangle are 15 by 19 feet.
Answer:
maximum value at (5, 9 )
Step-by-step explanation:
The vertex is the point on the graph where it goes from an increasing function to a decreasing function as x increases from left to right.
vertex = (5, 9 )
Since the function increases to the vertex then turns at the vertex and decreases.
It reaches a maximum value at the vertex of y = 9
