Answer:
f( g(x)) = 18 *x*x + 6
g( f(x)) = 6xx + 18
Step-by-step explanation:
we want f (g(x)) and g( f(x))
f = 2xx + 6 g = 3x
f( g(x)) = 2 *(3x)*(3x) + 6 = 18 *x*x + 6
g( f(x)) = 3*(2 xx + 6 ) = 6xx + 18
Answer:
133.20 degrees
Step-by-step explanation:
Since the straight line is equal to 180 degrees, you just need to subtract 180 by 46.8 to find the measurement of n. 180-48.2=133.20 degrees.
Surface area = 56 cm2
Explanation:
Area of square base = Side x Side = 4 x 4 = 16 cm2
Area of triangle = 1/2 x Base x Height = 1/2 x 4 x 5 = 10 cm2
Area of 4 triangles = 10 x 4 = 40 cm2
Surface area of pyramid = 16 + 40 = 56 cm2
