Answer:
The perimeter of triangle ΔABC is approximately;
(A) 20.0
Step-by-step explanation:
In ΔABC, the coordinates of the vertices are given as follows;
A(-4, 1), B(-2, 3), C(3, -4)
The length, 'l', of the sides of the triangle with known 'x', am]nd 'y' coordinates are given as follows;
Therefore, we have;
The length of segment 
= √((3 - 1)² + (-2 - (-4))²) = 2·√2 ≈ 2.83
The length of segment 
= √(((-4) - 3)² + (3 - (-2))²) = √74 ≈ 8.6
The length of segment 
= √(((-4) - 1)² + (3 - (-4))²) = √74 ≈ 8.6
The perimeter of a geometric shape is equal to the sum of the length of sides of the figure
The perimeter of triangle ΔABC = (The length of segment ) + (The length of segment ) + (The length of segment )
∴ The perimeter of triangle ΔABC = 2·√2 + √74 + √74 ≈ 20.0.
All you have to do in this problem is just find the pattern in the sequence. So like how did you get from 1 to 2. Then you continue to ask the question again like how did you get from 2 to 4.

Answer:
£55
Step-by-step explanation:
Multiplying the given ratio units by 11 tells you the answer.
4 : 5 = 44 : 55
Paul got £55.
In order to find the number times something is larger than something, you have to use division where you divide the larger number by the smaller number.
So:
I'm not sure how much you want to round to, but the answer is 387.6063183 times.
You can make sure by multiplying the smaller number by 387.6063183 and you should get the larger number:
