Answer:
AB = 6.5
Step-by-step explanation:
If you use the distance formula, you can find the answer.

Therefore, the distance between the points A(0, 1) and B(6, 3.5) is 6.5. Hope this helps!
Answer: b1/b1=h1/h2=10/12=15/h2 so use criss cross and equel to 15×12=10h2 both sides devide by 10 and equel 180/10=18
so h2=18
You have to multiply 7 3/4 to 9.
First, turn 7 3/4 to an improper fraction which is 31/4.
Next, you multiply 31/4 to 9/1(same thing as 9) across from each other.
Then, you get the answer 279/4(31 x 9 = 279 ;4 x 1 = 4; 279/4).
Last divide 279 to 4 and get 67.75( .75 = 3/4 ; 69 3/4).
try to add the all up then divide by 3
