How do i go about doing this problem?

23. 4 units

24. 4 units

The point C is on the number line at -1 and the point E is at 3. We count the number of units from C to 0, which is 1 and from 0 to E, which is 3. We add the sum, 3 + 1 = 4.

Another way to show it is 3 - (-1) = 3 + 1 = 4.

Thus CE = 4

We repeat the process for BD. -4 -(0) = -4 - 0 = -4. However, distances are positive so we report its opposite, 4.

Thus BD = 4

Therefore CE = 4 and BD = 4

answer: 4 (:

step-by-step explanation:

odd numbers are only divisible by 1 and itself.

even numbers are divisible by more than 1 and itself.

for example 6 is even because it is divisible by more than 1 and its self. 1 x 6= 6 ; 2 x 3= 6

and 7 is odd because only 7 x 1 equals seveb
