Answer:
L = 18 and w = 16
Step-by-step explanation:
The area of a rectangle is found by A = l*w. Since the length here is 2 more than the width or 2 + w and the width is w, substitute these values and A = 288 to solve for w.
To solve for w, move 288 to the other side by subtraction. Then factor and solve.
Set each factor equal to 0 and solve.
w - 16 = 0 so w = 16
w + 18 = 0 so w = -18
Since w is a side length and length/distance cannot be negative, then w = 16 is the width of the rectangle.
This means the length is 16 + 2 = 18.
Answer:
B. The function has an even degree.
Step-by-step explanation:
We have been given an image of a polynomial function. We are asked to choose the correct options about our given polynomial.
A. The function has a negative leading coefficient.
Upon looking at our given graph, we can see that it is an upward opening parabola, so leading coefficient can't be negative, therefore, option A is not true.
B. The function has an even degree.
Upon at our given graph, we can see that it is symmetric to y-axis, therefore it has an even degree polynomial and option B is the correct choice..
C. The function has zero turning points.
Upon looking at our given graph, we can see that as function approaches towards 0 from negative infinity it is decreasing. As function increases positive infinity from 0, it is increasing, therefore, our function has a turning point at , therefore, option C is incorrect.
D. The function has one x-intercept.
Since our function never intersects x-axis, therefore, function has no x-intercept and option D is incorrect as well.
