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)
Answer:
he first one and the third one
Step-by-step explanation:
This is to do with ratios, the idea behind it is that you see that the side of length 24 is an enlarged version of the side labelled 16. Using this you can see that the ratio of enlargement is 1.5, therefore x = 26/1.5 = 53/2

Answer:
x = -2
Step-by-step explanation:
Line q is the horizontal line y = 6, so the perpendicular line will be vertical. In order for it to go through the point (-2, 3), the equation must be ...
x = -2
