Henry says that you can apply the commutative property and associative properties to 5x + 10 and get 10x + 5. Is Henry correct?
olganol [36]

Answer:

no

Step-by-step explanation:

5x would be multiplying 5 and x. So, if x=4, then 5x would be 20, and 20+10=30. But if you did 10x+5, it would be 40+5 which is 45. Therefore, the answers would not be the same.

The difference of the square of a number and 24 is equal to 5 times that number. Find the negative solution.
SVEN [57.7K]

Answer:

n = -3

Step-by-step explanation:

The difference of the square of a number and 24 is equal to 5 times that number. Find the negative solution.

I'm going to call the number "n."

n² - 24 =  5n      subtract 5n from both sides to get the equation equal to zero

- 5n        -5n

n² - 5n - 24 = 0   factor the trinomial into the multiplicatin of two binomials

                          we need factors (numbers that multiply) to -24 that add up to

                          -5.  The only factors for -24 that will add up to -5 are -8 and 3.

(n-8)(n+3) = 0     set each binomial equal to zero and solve for n

n-8  =  0     or    n+3  =  0

 +8    +8               -3     -3

 n   =  8     or        n  = -3       n = -3 is the negative solution

2(6)-2x=3<br> CN someone answer? Use distributive property
Mandarinka [93]

Answer:

I think this is what you want:

2(6)-2x=3

We then see that 2(6) and 2(x) have two in common as a "coefficient" you could say, so we distribute and put parentheses around it.

2(6-x)=3

6-x=3/2

-x=-9/2

x=9/2
