Answer:
Step-by-step explanation:
Use the distance formula.
Subtract the x-coordinates and square the difference.
3 - 7 = -4; (-4)^2 = 16
Subtract the y-coordinates and square the difference.
4 - 2 = 2; 2^2 = 4
Add the differences and take the square root of the sum.
16 + 4 = 20; sqrt(20) = sqrt(4 * 5) = 2sqrt(5)
distance = 2sqrt(5)
You can use the distance formula which does the same thing.
Answer: 27
Step-by-step explanation:
3(2c+3)
If c=3, then the equation can be written as: 3(2(3)+3)
You would multiply 2 and 3 first
=3(6+3)
And then do distributive property
=18+9
Combine terms
= 27
Answer: 735
Step-by-step explanation:
Number of Plates
To find the number of radishes, first find the number of plates.
There are 21 tables with 5 plates per table so
P = 21 tables * 5 = 105 plates
Number of Radishes
Then find the number of radishes
There are 105 plates with 7 radishes per plate so
R = 105 plates * 7 = 735 radishes
Final Answer
735 radishes
