Answer 1

Answer:

51

Step-by-step explanation:

11+(-7)^2-9 - original

11+49-9 - square the -7, since its in brackets the negative applies too and a negative x a negative = positive, so it ends up as 7x7+49

60-9 - add both positives 11+49=60

51 - subtract 9 from 60, 60-9=51

(3x3 + 4x2 – 2+ 7) + (x + 2)

Answers

I hope that is right

Divident = Divisior x Quotient + Remainder

(3x³ + 4x² - 2 + 7)  = (x + 2) x (3x² - 2x) + (4x - 5)

(3x³ + 4x² - 2 + 7)  =  (3x³ + 4x² - 2 + 7)

What is division?

A division is a process of splitting a specific amount into equal parts. 

We have,

(3x³ + 4x² - 2 + 7) ÷ (x + 2)

We will divide using the long division method.

Divident = Divisior x Quotient + Remainder

Divident = (3x³ + 4x² - 2 + 7)

Divisor = x + 2

We will find the quotient and the remainder.

  x + 2 ) 3x³ + 4x² - 2 + 7 ( 3x² - 2x

             3x³ + 6x²                   [ sign is changed, 3x³ = -3x³ and 6x² = -6x²]

                    - 2x² - 5

                   - 2x² - 4x             [ sign is changed, -2x² = 2x² and -4x = 4x ]

                            4x - 5

Quotient = 3x² - 2x

Remainder = 4x - 5

Thus,

Divident = Divisior x Quotient + Remainder

(3x³ + 4x² - 2 + 7)  = (x + 2) x (3x² - 2x) + (4x - 5)

(3x³ + 4x² - 2 + 7)  =  (3x³ + 4x² - 2 + 7)

The perimeter of a rectangular tennis court is 228 feet. If the length of the court exceeds the twice the width by 6 feet, find its dimensions.

Answers

Answer:

Width= 36 Length=78

Step-by-step explanation:

width= w

length = 2w+6

perimeter = 2(l+w)

228=2(2w+6+w)

228 = 2(3w+6)

228=6w+12

216 =6w

w=36

width= w=36 ft

length = 2w+6 = 2(36)+6=78 feet

The three irrational numbers between 15 and 17 can be written as [tex]$\sqrt{231.44}\\[/tex], [tex]$\sqrt{244.57}\\[/tex], [tex]$\sqrt{277.67}\\[/tex].

What are irrational numbers?

An irrational number is a number that cannot be expressed as a fraction {p/q} for any integers {p} and {q}.

Given are irrational numbers between 15 and 17​.

Now, we can write -

A = 15² = 15 x 15 = 225

{A} = 225

B = 17² = 17 x 17 = 289

{B} = 289

The irrational numbers between 15 and 17 can be written as the square root of numbers between 225 and 289. So, we can write -

[tex]$\sqrt{231.44}\\[/tex]

[tex]$\sqrt{244.57}\\[/tex]

[tex]$\sqrt{277.67}\\[/tex]

Therefore, the three irrational numbers between 15 and 17 can be written as [tex]$\sqrt{231.44}\\[/tex], [tex]$\sqrt{244.57}\\[/tex], [tex]$\sqrt{277.67}\\[/tex].

What is arithmetic operations?

A number juggling activity is determined by consolidating operands with one math administrator. The built-in functions ADD, SUBTRACT, DIVIDE, and MULTIPLY can also be used to specify arithmetic operations.

Both the plus sign and the minus sign can be used as operators with prefixes or infixes. Only infix operators can be used to represent all other arithmetic operators.

Given cost of 2/5 pound of grapes is $2

2/5p = 2

where p = pound

p = (2 x 5)/2

1p = 5

1 pound = $5

Therefore the 1 pound of grapes cost $5.

there are 500 children in a school for the PT drill they have to stand in such a manner that the number of rows is equal to the number of columns.how many children would be left out in this arangement​

Answers

Answer:

16 children would be left out in this arrangement​

Step-by-step explanation:

Total number of children in a school = 500

For P.T. Drill number of rows = number of columns =x

The number of children who will be left out = 500−x^2  .

The square root of 500 gives remainder as 16 that means, the square of 22 is less than 500 by 16

To make it a perfect square = 500−16=484 Therefore, number of children left will be 16

= 16 children would be left out in this arrangement​
