I would first add 5 and 2 together, then multiply that by 3. Finally you would subtract the 1. After solving for what is inside the parentheses you would multiply it by 2 for your final answer.
2•(3(5+2)-1)
2•(3(7)-1)
2•(21-1)
2•(20)
40
√(- 9 ) / (( 4 - 7 i ) - ( 6 - 6 i )) = 3 i / ( 4 - 7 i - 6 + 6 i ) =
= 3 i / ( - 2 - i ) = - 3 i / ( 2 + i ) =

=
- 1 - 2 i
Answer:
None of the above
Step-by-step explanation:
=4+2y+7
x+8=(7x)+
(2y)+(4+8)=7x+2y+12
100 cm = 1 meter
<span>4.5 meter x 100 cm = 450 cm </span>
<span>450 cm / 4.5 cm = number of pieces of ribbon </span>
<span>450/4.5 = 100</span>
Answer:
10 centimeters.
Step-by-step explanation:
First, we need to remember what's the formula to get the volume of a rectangular solid and a cube.
The volume of the first equals:
Volume = Length x Width x Height
While the volume of the cube is:
where a is the edge.
We are given the measures of the rectangular solid so we can calculate its volume:
cubic cms.
Now, we know that both the volume of the rectangular solid and the cube are the same so we will use this information to calculate the edge of the cube.
![1000=a^3 \\\sqrt[3]{1000} =\sqrt[3]{a^3} \\10=a](https://tex.z-dn.net/?f=1000%3Da%5E3%20%5C%5C%5Csqrt%5B3%5D%7B1000%7D%20%3D%5Csqrt%5B3%5D%7Ba%5E3%7D%20%5C%5C10%3Da)
Thus the length of an edge of the cube is 10 centimeters
