Answer:  

Total Surface Area of the given regular pyramid = 153 units²

Step-by-step explanation:

Base length of the regular pyramid, l  = 9 units

Base width of the regular pyramid, w = 9 units

Height of the regular pyramid, h = 7 units

Perimeter of base = 3 × 9

                              = 27 units

\text{Area of base = }\frac{1}{\times Base\times Height\\\\Area = \frac{1}{2}\times 9\times 7=21.5\:\:units^2

\text{Now, Total Surface Area = }\frac{1}{2}\times p\times l+A\\\\\implies\text{Total Surface Area = }\frac{1}{2}\times 27\times 9+31.5

Hence, Total Surface Area of the given regular pyramid = 153 units²

If c(x)=5/x-2 and d(x)=x+3 what is the domain of (cd)(x)?. . And, if f(x)=7+4x and g(x)=1/2x, what is the value of (f/g)(5)?
Vesna [10]
1. The value of (cd)(x) is equal to the product of c(x) and d(x) which is equal to,
                                         5(x + 3) / (x - 2)
The function can take all real numbers except 2 because that would make the denominator 0. 

2. To answer, substitute first 5 to the given functions,
                      f(x) = 7 + 4x = 7 + 4(5) = 27
                      g(x) = 1/2x = 1 / (2)(5) = 1/10
Dividing 27 by 1/10 is 270.
