Answer:
2390.7 square meters
Step-by-step explanation:
(semicircle area) 30.5/2 = 15.4
15.4 x 15.4
= 232.5625 x 3.14
= 730.24625 x 2 = 1460.4
(square area) 30.5 x 30.5 = 930.25
930.25+ 1460.4= 2390.7 square meters

Hello,
Answer A
x²+4x+3=(x+3)(x+1)
x^3+6x²+11x+6=(x+1)(x²+5x+6)
x²+5x+6=(x+2)(x+3)
so
x^3+6x²+11x+6=(x+1)(x+2)(x+3) (Horner's method)
The average is 80*
80* + 80*=160 divided by 2 is 80*
