You first have to distribute the negative to the second pair of parenthesis. So the new equation would be 2n-4-4n+3. Next you combine like terms. So your final answer is -2n-1.
Solution
3(-x+(2x+1))=x-1
3(x+1)=x-1
3x+3=x-1 collect like terms
3x-x=-1-3
2x=-4 divide both side by 2
x=-4/2=-2
Answer:
Measure the diagonals, they should be 5 feet (3,4,5 triangle).
Step-by-step explanation:
As a more general answer, the diagonal measurements of ANY rectangle will be equal. You can calculate the correct measurement using A^2 + B^2 = C^2. A and B are the lengths of the sides and C is the length of the diagonals.
Answer:
Length of the fencing required = 201.06 meters
Step-by-step explanation:
Architect is planning a circular playground with diameter = 64 m
We have to calculate the fencing required to cover this playground.
Length of fencing = circumference of the playground
Since circumference of a circle = π × (Diameter)
= 64π
= 201.06 meters
Therefore, length of fencing required to keep the kids in a circle will be 201.06 meters.
