Answer:

2·8·7
8+2+7
12·5·3
3+5+12

Step-by-step explanation:

The properties of addition and multiplication allow you to rearrange and/or regroup the components of a sum or a product. That is the point of this exercise.

(2·8)·7 = 2·(8·7) . . . . parentheses have moved: associative property

2 + 7 + 8 = 8 + 2 + 7 . . . . order is rearranged: commutative property

5·3·12 = 12·5·3 . . . . . order is rearranged: commutative property

(3 +5) +12 = 3 +(5 +12) . . . . parentheses have moved: associative property

<em>Additional comment</em>

Whenever you're in doubt about the equivalence of numerical expressions, you can use your calculator to evaluate them. They will give the same result if they are equivalent. (You need a good scientific or graphing calculator that uses parentheses for this. Some seriously good calculators are available as low-cost phone apps.)

The Google search box also serves as input to the Google calculator. You can use an asterisk (*) for multiplication.

Alex_Xolod [135]

f(n)= n^2 -6n - 16

Set f(n) =0

n^2 -6n-16=0

Factor it

(n-8)(n+2)=0

Solve for n

n-8=0 n+2=0

n=8 and n =-2

Nolan Walker decided to buy a used snowmobile since his credit union was offering such low interest rates. He borrowed $4,400 at

Serhud [2]

Answer:

He paid $253.09 in interest.

Step-by-step explanation:

To find how much did he pay in interest, we use the simple intrest formula, that is given by:

$I = Prt$

In which I is the value paid in interest, P is the money borrowed, r is the yearly interest rate and t is the time.

In our problem, we have that:

He borrowed $4,400, so $P = 4,400$

At 4.75% yearly. We measure the time in days, so we have to divide this value by 365. So $r = \frac{0.0475}{365}$ .

From December 26, 2019 to February 21, 2021, there are 422 days, so $t = 422$ .

$I = Prt$

$I = 4,400\frac{0.0475}{365} 422$

$I = 253.09$

He paid $253.09 in interest.

Simplify the expression

Ronch [10]

Answer:

(3 x)/(5 x + 2)

Step-by-step explanation:

Simplify the following:

(3 x^2)/(5 x^2 + 2 x)

Hint: | Factor common terms out of 5 x^2 + 2 x.

Factor x out of 5 x^2 + 2 x:

(3 x^2)/(x (5 x + 2))

Hint: | For all exponents, a^n a^m = a^(n + m). Apply this to (3 x^2)/(x (5 x + 2)).

Combine powers. (3 x^2)/(x (5 x + 2)) = (3 x^(2 - 1))/(5 x + 2):

(3 x^(2 - 1))/(5 x + 2)

Hint: | Evaluate 2 - 1.

2 - 1 = 1:

Answer: (3 x)/(5 x + 2)
