Answer:
Volume= 268 ft³
Step-by-step explanation:
Volume of sphere=4/3 pie r^3
Diameter =8 ft
⇒Radius = 4 ft
V= 4/3×3.14×4³
v=268
If you would like to solve the equation a^2 - 8*a + 12 = 0 for a, you can calculate this using the following steps:
a^2 - 8*a + 12 = 0
(a - 6) * (a - 2) = 0
1. a = 6
2. a = 2
The correct result would be B; 2, 6.
Answer:
(a) i and ii: 2b-2 = b+b-2
(b) i and iii: c+d = d+c
(c) ii and iii: a + 2b - 1 = a+b-1+b
(d) i and iii: x+(y-z) = x-(z-y)
(e) ii and iii: (a-1)² = (1-a)²
(f) i and ii: 3a-b-1-1 = 3a+b-2-2b
Step-by-step explanation:

Answer:
The solution to the system of equations be:
Step-by-step explanation:
Given the system of equations
x + y = 12
-x + 2y = 15
Let us solve the system of equations by elimination
adding the equations
solve 3y = 27 for y
divide both sides by 3
Simplify
For x+y=12 plug in y = 9
Subtract 9 from both sides
Simplify
Therefore, the solution to the system of equations be:
