Answer:
Fifteen is a factor of the number because both 3 and 5 are prime factors.
Step-by-step explanation:
2^3 * 3^2 * 5
= 2 * 2 * 2 * 3 * 3 * 5
As you can see from, the prime factors are 2, 3, and 5.
3 × 5 = 15, option A is correct.
The answer would be D.) 6
FH = 2*JH = 2*4 = 8 cm
Area(EFJH) = FH²/2 = 8²/2 = 64/2 = 32 cm²
AC = 2*JC = 2*9 = 18 cm
Area(ABCD) = AC²/2 = 18²/2 = 324/2 = 162 cm²
Area of the shaded region = 162 - 32 = 130 cm²
