The opposite operation of squaring is to find the square root. I dunno what the original equation is so I can’t help with that
Answer:
B is (7,-4) C is (7,-2) D is (5,0)
Step-by-step explanation:
Trust me
We know that
<span>The nine radii of a regular Nonagon divides into 9 congruent isosceles triangles
</span>therefore
[the area of <span>a regular nonagon]=9*[area of isosceles triangle]
</span>[area of isosceles triangle]=b*h/2------> 15*20.6/2----> 154.5 cm²
so
[the area of a regular nonagon]=9*[154.5]------> 1390.5 cm²
the answer is
1390.5 cm²
We have to find the area of the floor in order to know how many square meters of flooring they need.
The area of the floor is:
42 m* (39 m)= 1,638 m^(2)
They need 1,638 m^(2) of flooring.
Hope this helps~
