How much longer is cd compared to ab ? round your solution to 2 decimal points.

Explanation:

Use the distance formula (Pythagoras) between two points to find the length of each segment:

1) Segment AB:

2) Segment CD:

3) Difference:

CD is 0.66 units longer than AB.

Step-by-step explanation:

Coordinates of A and B are (-11, 4) and (-8, 8)

Therefore, from the formula of distance between two points (x, y) and (x', y')

d =

Distance AB =

AB =

AB = 5

Similarly distance between C (3, 2) and D(7, -2) will be

CD =

CD =

CD = 5.66

Difference between the lengths of AB and CD = 5.66 - 5

= 0.66

Therefore, CD is 0.66 units longer than AB.

13

step-by-step explanation:

divide the cost of the total of sodas you bought by the cost of one soda, for example:

$24.57 divided by $1.89 is 13 which means you bought 13 sodas

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer
