The answer is -4 because two negatives is the same as adding so -6 + 2 = -4
Answer:
The simplified form is 
Step-by-step explanation:
To simplify the expression given to use, we need to reduce the given expression in its simplest form. There should not be any possibility for the further cancelling out of the division terms, if any.
Now the expression that is given to us is:

Here we will simplify it, as follows:

So this is the required simplified form.
The main formula of a spherical surface area is SA= 4 x Pi x r²
the circumference is C= 19cm =2 Pi r, so r = C/ 2Pi = 19 / 6.28 =3.02cm
so the surface area can be found by computing
SA= 4x 3.14x 3.02² =114.5, the nearest square centimeter is <span>A) 114 cm^2</span>
Perimeter of a square = 4L
4L = (8x+12)ft
L= (2x+3)ft
