Answer:
6
Step-by-step explanation:
You are looking for the cross section of ask three circles. This is true for the smallest part, with the number 6 in it.
X2=9 has only one solution, which is 4.5
Answer:
Step-by-step explanation:
b(a + 1) + a = b*a + b + a = ab + b + a
1) b(2a +1 ) = b*2a + b*1 = 2ab + b Not equivalent.
2)a + (a +1)*b = a + ab+ b Equivalent
3) (a +1)(b+ a) = a*(b +a) + 1*(b+a) = ab+ a² +b + a Not equivalent.
4) (a + 1)b + a = ab+ b + a Equivalent
5) a + b(a+1) = a +ab + b Equivalent
6) a + (a +1) + b = a + a + 1 + b = 2a + 1 +b Not equivalent.
7) a(b +1) + b = ab + a + b Equivalent
Answer:
Javier,16,12
Step-by-step explanation:
From the first bag, we can pull a 1,2 or 3. That would go on the first line of the tree diagram
From the 2nd bag, we can draw a 4,5, or 6. That goes on the the second line under each number
From the 3rd bag, we can draw a 7,8, or 9. That goes on the the third line under each number
Javier drew the correct tree diagram.
1,3,5,7,9 are odd numbers. We must have at least 2 of these numbers
1,4,7 2,5,7 3,4,7
1,4,9 2,5,9 3,4,9
1,5,7 3,5,7
1,5,8 3,5,8
1,5,9 3,5,9
1,6,7 3,6,7
1,6,9 3,6,9
There are 16 total where there are at least two odd numbers
Multiples of 4 are 4 and 8
We must have either a 4 or an 8 but not both
1,4,7 2,4,7 3,4,7
1,4,9 2,4,9 3,4,9
1,5,8 2,5,8 3,5,8
1,6,8 2,6,8 3,6,8
There are 12 outcomes
