Answer: Draw rectangle put 149m at the top and bottom and 76m at the side now add and you 450m
The quadratic equation has two solutions if b^2 - 4ac > 0
Given the equation ax^4 + bx^2 + c=0
Substitute into the formula to have:
The equation becomes aP^2 + bP + c = 0
For us to have a unique solution, the discriminant b^2 - 4ac must be greater than zero. Hence the quadratic equation has two solutions if b^2 - 4ac > 0

Then


Answer:
D) 8
Step-by-step explanation:
3x - 7 - 2x + 5 = 6
3x - 2x = 6 + 7 - 5
x = 8
Note: 6 + 7 -5 = 13 -5 = 8
