ABCDE is a regular pentagon which consists of 5 equal triangles.
Area of the pentagon ABCDE:
A = 5 * 1.41 * 9.7 / 2 = 683.85 / 2 = 341.925 ≈ 341.9 cm²
Answer: The area of the pentagon ABCDE is 341.9 cm².
Answer:
30
Step-by-step explanation:
x= -2 and y= 3
Hence, simply put it in the equation:
3x + 4y^2
3(-2) + 4(3)^2
-6 + 4(9)
-6 + 36
30

Answer:
-10
Step-by-step explanation:
9^-8 x 9^-2 = a^b
We know that x^y * x^z = x^(y+z)
9^-8 x 9^-2 = 9^(-8+-2) = 9^(-10)
a= 9
b = -10
