Answer:
625 unit²
Step-by-step explanation:
Surface area of a rectangular pyramid :
Area of base * 4(area of triangular side)
Area of base = length * width
Area of base = 15 * 15 = 225
Height of triangular side = 15
Area of triangle = 1/2 * base * height
Area of triangle = 1/2 *15 * 15 = 112.5 unit²
Surface area = 225 + 4(112.5)
Surface Area = 225 + 450
Surface Area = 625 unit²
12 and 23
- Two numbers are relatively prime only when they have 1 as the common factor . or in other words they can not be divided by any other number other than 1 and itself.
- To find
- relative prime
- of two numbers we need to find the HCF of the numbers. If the HCF is 1, then the two numbers are said to be relatively primes or in other words only 1 should be common as factor.
- factor of 23 = 2, 2, 3, 1
here only 1 is a common factor.

Answer:
The value of g[f(2)] = 13
Step-by-step explanation:
Given functions:
f(x) = x²
g(x) = 3x + 1
Find:
The value of g[f(2)]
Computation:
f(x) = x²
By putting x = 2 in f(x)
f(x) = x²
f(2) = 2²
f(2) = 2 × 2
f(2) = 4
So the value of f(2) = 4
Value of f(2) putting in g(x)
g(x) = 3x + 1
g(x) = 3x + 1
g[f(2)] = 3[f(2)] + 1
We know that f(2) = 4
So,
g[f(2)] = 3[f(2)] + 1
g[f(2)] = 3[4] + 1
g[f(2)] = 12 + 1
g[f(2)] = 13
The value of g[f(2)] = 13
