What two numbers multiply to __ and add up to __?1. Multiply -15 add -2
2. Multiply -32 add -4
3.multiply -14 add -5
4. Multiply -24 add 5

Answers

Answer 1
Answer: Arrange the factors of the product so that when added you get the sum:
1. The factors of 15 are 3 and 5 or 1 and 15. You are looking for the pair that is two apart, which are 3 and 5. Because they add up to be negative 2, 5 must be negative, so the two numbers you get are 3 and -5. The rest can be solved similarly:
2. (Out of 1 and 32, 2 and 16, and 4 and 8, only 4 and 8 works) -8+4=-4, -8*4=-32
3. (Out of 1 and 14, and 2 and 7, only 2 and 7 works) -7+2=-5, -7*2=-14
4. (Out of 1 and 24, 2 and 12, 3 and 8, and 4 and 6, only 3 and 8 works) -3+8=5, -3*8=-24.
Answer 2
Answer:

Answer:

-3 + 8 = 5, -3 · 8 = -24

the Mclntosh family went apple picking. they picked a total of 115 apples. The family ate a total of 8 apples each day. after how many days did they have 19 apples left?

Answers

In the given question, all the information's that are required is already provided. based on these information's the correct answer can be easily deduced. The McIntosh family picked a total of 115 apples. the family ate a total of 8 apples per day. It is required to find the day after which there will be 19 apples left from the total of 115. Then firstly let us subtract 19 apples from the total of 115.
Number of apples left after deducting 19 apples = 115 - 19
                                                                             = 96
Now
8 apples are eaten by the McIntosh family in = 1 day
96 apples will be eaten by the McIntosh family in = 96/8
                                                                               = 12 days
So after 12 days, 19 apples will be left with the McIntosh family.

Answer:

19 apples will be left with the McIntosh Family

Mrs. Eaton's class is participating in the "Box Tops for Education" campaign. On the first day, herclass collected 2 tops. On the third day, her class collected 8 tops. Let D represent each collection
day and N represent the number of tops collected on that day.
Based on the situation, John claims the number of tops collected can be modeled by an exponential
function. Riley disagrees and claims the number of tops can be modeled with a linear function. What
is the number of tops collected on the sixth day based on the exponential model? What is the
number of tops collected on the sixth day based on the linear model?

Answers

Given:

Day        Tops
1               2
2               ?
3               8

Exponential model:
d(x) = 2^x
d(6) = 2⁶ = 2 x 2 x 2 x 2 x 2 x 2 = 64 tops

LInear:
d(x) = 2 + 2x
d(6) = 2 + 2(6)
d(6) = 2 + 12
d(6) = 14 tops

Answer:

Exponential: 64

Linear: 17

What property does the statement show? ( 4 x 8 ) x 3 = ( 4 x 4 ) x 3

Answers

Answer: Associative property of multiplication.

Step-by-step explanation:

The property demonstrated by the statement "(4 x 8) x 3 = (4 x 4) x 3" is the associative property of multiplication.

The associative property of multiplication states that you can change the grouping of numbers in a multiplication expression without changing the result. In this case, both sides of the equation involve multiplication, and the numbers being multiplied are grouped differently but still yield the same result.
commutative property of multiplication

Prime or composite 52

Answers

52 is composite 
prime can be divided evenly only by 1, or itself
but 52 can divided by 2,4,13, etc...
hope it helps
If it is prime, it cannot be split in 2 numbers that multiply to equal it. Look at the last number of the number to get a hint first. The last number of 52 is a 2. If you recall, any number that ends ina  2 or 0 can be divided by 2:

  52
  /  \
2  26
    /  \
   2   13 

There the number is fully factored.
