La propiedad (a, byc son números reales, variables o expresiones algebraicas)1. Propiedad de distribución a • (b + c) = a • b + a • c2. Propiedad conmutativa de la adición a + b = b + a3. Propiedad conmutativa de la multiplicación a • b = b • a4. Propiedad asociativa de la adición a + (b + c) = (a + b) + c
Answer:
B
Step-by-step explanation:
because the answer matches the equation
If we join the Center with different corners of the polygon,we find 10 Isoceles triangle with equal side=9.14cm, Making an angle of 36° between the equal sides.
Area of 1 triangle= a*b*sinC/2
= 9.14*9.14*Sin36°/2
= 9.14*9.14*0.587/2
=24.51 cm^2
Area of 10 triangle= 24.51*10
= 245.1cm^2
To answer that think of this as how many groups of 7/8 cups of salad are needed.
If Marion is with four friends, she need salad for five total people.
She will need five groups of 7/8 cups of salad.
This is represented as 5 x 7/8.
5 x 7/8 = 4 3/8 cups of salad
