The two numbers that multiply to 24 and add to 2 are -4 and -6. You can find these through the process of elimination with the equations x*y=24 and x+y=2.
The two numbers that multiply to 24 and add to 2 are -4 and -6. Let's find out how:
Note that the two numbers are negative which is why they add to a positive number when multiplied.

Answer: Adam will run 12 miles in 1 hour.
Step-by-step explanation:
Ok, so we know 4 miles in 20 minutes, correct?
Multiply 20x2. You will get 40. Then, multiply 4x2. That is 8. So in 40 minutes he ran 8 miles. So if we multiply 20x3, we would get 60 minutes which is an hour. So we need to multiply 4 by 3–12.
Answer: 12 miles
Step-by-step explanation:
The square of 0.9 will result to 0.81, and the squareroot of 0.81 is equal to 0.9.
Squares are the numbers gotten after multiplying a value by itself. While the squareroot of a number is a number whose square is the given number. Hence, both are vice versa methods.
We shall solve for the square root of the number 0.81 as follows;
0.81 = (0.9 × 0.9)
by taking the squareroot of both sides we have;
√0.81 = √(0.9 × 0.9)
√0.81 = √(0.9)²
√0.81 = 0.9
Therefore, the square of 0.9 will result to 0.81, and the squareroot of 0.81 is equal to 0.9

The outcomes that fall in A∩B are {5} only.
The intersection of two or more events is the number of outcomes that are common to both events. It is represented by an inverted-U sign, '∩'.
We are said that Ramona is playing a board game with two number cubes.
∴ All possible outcomes when the cubes are rolled by Ramona are:
(1,1) (1,1) (1,1) (1,1) (1,1) (1,6)
(2,1) (2,2) (2,3) (2,4) (2,5) (2,6)
(3,1) (3,2) (3,3) (3,4) (3,5) (3,6)
(4,1) (4,2) (4,3) (4,4) (4,5) (4,6)
(5,1) (5,2) (5,3) (5,4) (5,5) (5,6)
(6,1) (6,2) (6,3) (6,4) (6,5) (6,6)
We are given two outcomes,
A = {the sum of the number cubes is odd}
B = {the sum of the number cubes is divisible by }
When we sum numbers on cubes for each outcome, we get
2 3 4 5 6 7
3 4 5 6 7 8
4 5 6 7 8 9
5 6 7 8 9 10
6 7 8 9 10 11
7 8 9 10 11 12
The outcomes with odd sum are:
(1,2) (1,4) (1,6)
(2,1) (2,3) (2,5)
(3,2) (3,4) (3,6)
(4,1) (4,3) (4,5)
(5,2) (5,4) (5,6)
(6,1) (6,3) (6,5)
∴ A = {3, 5, 7, 9, 11}
The outcomes with sum divisible by 5 are:
(1,4) (2,3) (3,2) (4,1) (4,6) (5,5) (6,4)
∴ B = {5,10}
Now, we check for common terms in A and B to find A∩B.
We only have one common term in A and B, which is 5.
∴ A∩B = {5}
