Answer:
A
Step-by-step explanation:
Given
4n² + 4(4m³ + 4n² ) ← distribute terms in parenthesis by 4
= 4n² + 16m³ + 16n² ← collect like terms
= (4n² + 16n²) + 16m³
= 20n² + 16m³
= 16m³ + 20n² ← in standard form → A
Answer:
The answer is No.4
Step-by-step explanation:
Giventhat the formula of a cube is, V = x³ where x determine the length of the edge of the cube. By using this formula, you may find out the volume of a rubix cube :
x = 5.7cm
V = 5.7³
= 185.193cm³
The question ask us to find the volume of 2 combined cubes so, we can just multiply it by 2 :
V = 185.193 × 2
= 370.386cm³
V solid = π *
* 13 / 3 + π *
* 2 = 3.14 * 25 *13 / 3 + 3.14 * 50 = 340.16 + 157 = 497.16 ≈ 497.20 cubic centimeters;

Answer:
B. Multiply 6 by 3
Step-by-step explanation:
Do the opposite order of what Hannah did. The last step that she did was divide by 3, so you would multiply the result (6) with 3:
B. Multiply 6 by 3
Your step by step for getting the number Hannah started with:
First, multiply 6 with 3:
6 x 3 = 18
Next, subtract 4:
18 - 4 = 14
Next, divide by 2:
14/2 = 7
Hannah started with the number 7.
