c) 3(√3+1)^(2)-2(√3-2)x^(2)

Answers

Answer 1
Answer: \sqrt{(5 - 1)^(2)} + √(20)

\sqrt{4^(2)} + √(4 * 5)

√(16) + √(4) √(5)

4 + 2 √(5)

4√(5) + 2 √(5)

6 √(5)


\sqrt{(10 - 3)^(2)} + √(20 * 18)

\sqrt{7^(2)} + √(4 * 9 * 5 * 2)

√(49) + √(36 * 10)

7 + √(36)√(10)

7 + 6√(10)

7√(10) + 6√(10)

13√(10)


\sqrt[3]{(3 + 1)^(2)} - \sqrt{(3 - 2)x^(2)

\sqrt[3]{4^(2)} - \sqrt{x^(2)



\sqrt[3]{8} \sqrt[3]{2} - x

2\sqrt[3]{2} - x

Answer:

Step-by-step explanation:

You would do 2[3]+3 because you plug in the three for the x and it gives you 9 if you use a calculator be sure to use [ ] where needed.

Answer:

9

Step-by-step explanation:

Plug in 3 where x is.

2(x) + 3

2(3) + 3

Two times 3 equals 6, and six plus 3 equals 9.

So the answer is 9

Ben needs to buy orange juice. He can buy 64 fl oz at the grocery store for $2.00, or he can buy 256 fl oz at the wholesale club for $7.50| a) Find the unit price for the grocery store orange juice. Round your answer to the nearest thousandth.| b) Find the unit price of the wholesale club orange juice. Round your answer to the nearest thousandth.| c) Where should ben buy orange juice ifhe wants the best deal? Explain.

Answers

2. unit price = $ ÷ oz 
a) 64 fl oz for $2 = 2/64 ≈ $0.031 per ounce 
b) 256 fl oz for $7.5 = 7.5/256 = $0.029 per ounce 
c) buy wholesale because 0.029 < 0.031 

3. unit rate means 1 for the miles 
3/10 in ÷ 7/8 mi 
= 12/35 inches per mile ...

The quotient of the square of a number n and the cube of n increased by 5.

Answers

Answer:    (n^2)/((n + 5)^3)

Step-by-step explanation:

Now, a quotient means that we have a division.

The square of n is n^2

the cube of n increased by 5 is a little bit more tricky, this may refer to:

"the cube of n, increased by 5" that will be n^3 + 5

or "the cube of n increased by 5" that will be (n + 5)^3

As you did not write the comma, i will use the second option.

Then:

"The quotient of the square of a number n and the cube of n increased by 5."

is

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

Answer:

n^2/n^3+5

Step-by-step explanation:

First we are gonna analyize it.

Now: The quoient is division. Square= ^2 Cube=^3

Increased=Add

n=variable

So after doing everything you will get= n^2/n^3+5

How many feet lower is-282 than -68

Answers

Your equation is

-282 - (-68) =

when you subtract a negative, you "take away" that negative from the other value. The net result of that is adding the number. So the rule is minus negative means plus positive.

-282 - (-68) =
-282 + 68 = -214
-282 is -214feet than -68
