When it comes to finding points on a graph, think of the saying, "you have to learn how to walk before you climb."
Answer:
5
Step-by-step explanation:
x^2 - 10x + 16 = 0
factor
(x - 2)(x - 8) = 0
roots
x = {2, 8}
mean of roots
a = (2 + 8) /2
a = 5
If you let x represent the width of the rectangle, then you can write the equation for area as
.. x(2x +5) -63 = 0
This has positive solution x=4.5.
The rectangle is 4.5 meters by 14 meters.
4 is equal to 2*2 (double the 2 is 4)
1 over 3 since its rise over run and the x would be on the bottom and since you dont have a y it would be 1
