Step-by-step explanation:
Given the logarithm function
For logarithmic equations, 
is equivalent to 
such that
and 
In current case:
Substituting the values of 
and 
into the equation
Answer: Choice C) 124 square cm
------------------------------------------------------------------
Explanation:
Let's calculate the area of the trapezoid shown
b1 and b2 are the parallel bases; h is the height of the 2D trapezoid
b1 = 2
b2 = 5
h = 1.5
A = h*(b1+b2)/2
A = 1.5*(2+5)/2
A = 1.5*7/2
A = 10.5/2
A = 5.25
The area of one 2D trapezoid is 5.25 sq cm
There are two of these trapezoids that form the base faces of the trapezoidal prism. So the total base area is 2*5.25 = 10.5 sq cm
Keep this value (10.5) in mind. We'll use it later.
------------
Now onto the lateral surface area (LSA)
It turns out that the formula for the LSA is
LSA = p*d
where
p = perimeter of the trapezoid shown
d = depth or height of the 3D trapezoid (I'm not using h as it was used earlier)
This formula works for any polygonal base. It doesn't have to be a trapezoid.
In this case the perimeter is,
p = 1.7+2+2.65+5
p = 11.35
So
LSA = p*d
LSA = 11.35*10
LSA = 113.5
Add this LSA to the base area found earlier
10.5+113.5 = 124
The total surface area is 124 square cm
Answer:
y=2x-10
2y=x-8
since the second equation equals 2y and the first is y that means the first equation times 2 equals the other one
4x-20=x-8
-x
3x-20=-8
+20
3x=12
x=4
then lets just plug it in
2y=4-8
simplefy
2y=-4
y=-2
(4,-2)
