Answer:
36≤x≤48
Step-by-step explanation:
Let x represents the height of the child if a child must be at least 36 inches, this means that the child can has a height greater than or equal to 36in. This is expressed as;
x≥36
If the same child has height of no more than 48in, this can be expressed as;
x≤48
Combining both inequality
If x ≥36, this means 36≤x
Combining with x≤48 will give the compound inequality;
36≤x≤48

Answer:
x = 2
Step-by-step explanation:
The square of the tangent is equal to the product of the secant lengths to the near and far circle intersections.
(x +4)² = (2x -1)(2x -1 +9)
0 = (2x -1)(2x +8) -(x +4)² = (4x² +14x -8) -(x² +8x +16)
0 = 3x² +6x -24 = 3(x² +2x -8) = 3(x +4)(x -2)
This has solutions x = -4 and x = 2. Only the latter works in this geometry.
x = 2
