Step-by-step explanation:

The first step to solving this is to write the number in exponential form
2

=

since the bases are the same,, set the exponents equal to one another
-IxI = 7
now change the signs on both sides of the equations
IxI = -7
this equation is false for any value of x because the absolute value function needs to always be positive or 0,, which is not the case for this expression
x ∈ ∅
this means that the answer to your question is x ∈ ∅

Answer:
180 sq. in.
Step-by-step explanation:
The formula for the volume of a circular cone is V = (πr^2h)/3
So, 900 = (15πr^2)/3
2700 = 15πr^2
180 = πr^2 = area of the circular base
Here, trapezoid is composed of two triangles, and one rectangle.
So, Area of rectangle = 4 * 7 = 28 cm²
Area of a triangle = 1/2 * 3 * 7 = 21/2 = 10.5 cm²
Area of Trapezoid = area of rectangle + 2(area of triangle)
= 28 + 2(10.5)
= 28 + 21 = 49
In short, Your Answer would be 49 cm²
Hope this helps!
