9(2j+7+5j) Foil this out to get 18j+7+45j then 63j+7
Answer: 18j+7+45j , 63j+7 I think
For perimeter you add all of the sides but for area you multiply each side
Answer:
We must add 400 ml of water.
Step-by-step explanation:
We can use the following equation:
Where:
- C(i) is the initial concentration of the solution (80%)
- C(f) is the final concentration of the solution (30%)
- V(i) is the initial volume (150 ml)
- V(f) is the final volume
Now, we just need to solve the equation for V(f).
Therefore, we must add 400 ml of water.
I hope it helps you!
Answer:
<u><em>30cm</em></u>
Step-by-step explanation:
Given data
When are square is cut diagonally into two parts
The resulting shape is a triangle
hence the area of the square = 50+50 = 100cm^2
The length of each side of the square = √100= 10cm
likewise the diagonal of the square = 10cm
<u><em>Hence the perimeter of the resulting triangle= 10+10+10= 30cm</em></u>
I think what you are trying to ask is what number is divisible by three and nine
multiply 3 and 9 to get your answer
= 27
27 because it can be divided by 3 and = 9 and can be divided by 9 and = 3
