Answer:
<em>y > -x/2 or x > 2y</em>
To find the height, you would first multiply the length and width. You would get 56. Set that equal to 280 with an x to represent height. 280=56x. Then, you would divide 56 on both sides which leaves you with 5=x. So, your height would be 5 meters.
The zeros are the points on the x-axis where the graph intersects.
For factorization, you do (x - the zero) for each zero, and multiply them together.
7. A. The zeros are -2 and 4.
The factorization is (x + 2)(x - 4)
7 B. The zeros are 1 and 3.
The factorization is (x - 1)(x - 3)
4x^2+28x+49
4x^2+14x+14x+49
2x(2x)+2x(7)+7(2x)+7(7)
2x(2x+7)+7(2x+7)
(2x+7)(2x+7)
(2x+7)^2
The missing term is 28.
