Answer:
y = 2/5
Step-by-step explanation:
Add the total faces: 30 + 20 + 12 = 62
Using the given equation: V + F = E +2
You have F = 62, V = 120
Now solve for E:
120 + 62 = E +2
Simplify:
182 = E +2
Subtract 2 from both sides:
E = 182 - 2
E = 180
It has 180 edges.
Answer:
U = x + 4 and V = 2y^5.
Step-by-step explanation:
Square root of (x + 4)^2 = x + 4
Square root of 4y^10 = 2y^5
U = x + 4 and V = 2y^5.
(U - V)^2 = U^2 - 2UV + V^2
= (x + 1)^2 - 2 (2y^5 (x + 1) + 4y^10
= (x + 1)^2 - 4y^5 (x + 4) + 4y^10
Answer:
The original equation contains 3 multiplications.
When multiplying numbers, the order that they are in doesn't matter so 3 *2 is the same as 2 * 3.
This would make D, the same.
D) (3 × 2)×(5 × 6)
