Subtract the length from the perimeter because length + width = perimeter so 46ft - 11ft = 55ft
All you need is to solve the problem
4-2|n+6|>=2
subtracting 4 from both sides
-2|n+6|>=-2
dividing by -2 and flipping sign of inequality
|n+6|<=1
-1<=n+6<=1 subtracting 6 from both sides
-7<=n<=-5
the conjunction will be -7<=n and -5>= n
which is choice a
Explanation:
f(x) = (x-4)(x+2)
1) For x-intercept, y will be 0
<u />
<u>x-intercept</u>: (4, 0), (-2, 0)
2) For vertex: x = -b/2a where ax² + bx + c
<u>Quadratic function</u>:
<u>vertex</u>:
y: (x-4)(x+2) = (1-4)(1+2) = -9
ordered pair of vertex: (1, -9)
3) For y-intercept, x will be 0
<u>y-intercept</u>: (0, -8)
