URGENT! B is the midpoint of line segment AC. If AB = 4x + 1 and AC = 5x + 20, find the length of BC.

25 units.

Step-by-step explanation:

Given: B is the midpoint of line segment AC.

If and , then we have

Multiply 2 on both sides, we get

Now, AC = 5(6)+20 =30+20=50 units

Then, BC=  

Hence, the length of BC is 25 units.

step-by-step explanation:

to find the total number of combinations, multiply the quantity of each item by each other:

2 pairs of shoes x 3 pairs of shorts = 6 different combinations.
