Answer:
Step-by-step explanation:
Considering John's height as 
, saying that his height is at least 5 feet tall, it implies that the lowest height for John is 
So, inequality is
Answer: x=−2 or x=8
Step-by-step explanation:
Step 1: Factor left side of equation.
2(x+2)(x−8)=0
Step 2: Set factors equal to 0.
x+2=0 or x−8=0
x=−2 or x=8
48.7 rounded to one significant figure would be 50
We know that
[lateral surface area of a regular triangular pyramid]=3*[area of one <span>equilateral triangle]
so
[area of one </span>equilateral triangle]=lateral surface/3-----> 81/3-----> 27 ft²
[<span>surface area of the regular triangular pyramid]=lateral area+area of the base
area of the base is equals to the area of the lateral sides because are </span>equilateral triangles
therefore
area of the base=27 ft²
[surface area of the regular triangular pyramid]=81+27----> 108 ft²
the answer is
<span>the surface area of the regular triangular pyramid is 108 ft</span>²
