a=0 b=6 c=4 on edge exercise
Step-by-step explanation:
Answer:
x=# of boys
x+7=# of girls
x+x+7=25
2x+7=25
2x=25-7
2x=18
x=18/2
x=9 boys
x+7=16 girls

Answer & Step-by-step explanation:
For this problem, we will use the distance formula.

For our (x1, y1), we will use (-3, 1). For our (x2, y2), we will use (1, 5). Now let's plug in our numbers and solve the problem.





So, the distance between (-3,1) and (1,5) is 5.657 units.
Answer:
the answer if the first picture
Step-by-step explanation:
the second one is the explanation
So,
First, we find the prime factored form (P.F.F.) of 65 and 91.
P.F.F. of 65: 5 * 13
P.F.F. of 91: 7 * 13
Find the common numbers
13
13 = G.C.F.
Note: This method works for finding any G.C.F. (find common primes)
