Given :

⠀

To Find :

⠀

Solution :

We know that,

[tex]\qquad { \pmb{ \bf{Length \times Width = Area_{(rectangle)}}}}\:[/tex]

So,

Let's assume the length of the rectangle as x and the width will be (x – 4).

⠀

Now, Substituting the given values in the formula :

[tex]\qquad \sf \: { \dashrightarrow x \times (x - 4) = 45 }[/tex]

[tex]\qquad \sf \: { \dashrightarrow {x}^{2} - 4x = 45 }[/tex]

[tex]\qquad \sf \: { \dashrightarrow {x}^{2} - 4x - 45 = 0 }[/tex]

[tex]\qquad \sf \: { \dashrightarrow {x}^{2} - 9x+ 5 x - 45 = 0 }[/tex]

[tex]\qquad \sf \: { \dashrightarrow x(x - 9) + 5(x - 9) = 0 }[/tex]

[tex]\qquad \sf \: { \dashrightarrow (x - 9) (x + 5) = 0 }[/tex]

[tex]\qquad \sf \: { \dashrightarrow x = 9, \: \: x = - 5}[/tex]

⠀

Since, The length can't be negative, so the length will be 9 which is positive.

⠀

[tex]\qquad { \pmb{ \bf{ Length _{(rectangle)} = 9\:m}}}\:[/tex]

[tex]\qquad { \pmb{ \bf{ Width _{(rectangle)} = 9 - 4=5\: m}}}\:[/tex]

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

The length is 9m and the width is 5m.

This is defined as is a quadrilateral with four right angles and the area is calculated as Length × width.

Let's assume length is x and width is (x-4).

We have x × (x-4) = 45m²

x² - 4x = 45

x² - 4x - 45 = 0

x² - 9x + 5x -45 = 0

x(x-9) +5 (x-9)

(x+5)(x-9) = 0

x = -5 or x = 9

x is therefore 9m and the width is (9-4) = 5m

Answer:

15% of 25

Step-by-step explanation:

Given the following questions:

25% of 15
15% of 25

We find the answer by using the formula to calculate percentage for both questions.

Question one:
[tex]\frac{p\times n}{100}[/tex]
[tex]\frac{25\times15}{100} =25\times15=375\div100=3.75[/tex]
[tex]=3.75[/tex]

25% of 15 is 3.75

Question two:
[tex]\frac{p\times n}{100}[/tex]
[tex]\frac{15\times 25}{100}=15\times25=375\div100=3.75[/tex]
[tex]=3.75[/tex]

15% of 25 is 3.75

Finally:
[tex]3.75=3.75[/tex]

[tex]15-3.75=11.25[/tex]
[tex]25-3.75=21.25[/tex]
[tex]11.25 < 21.25[/tex]

Which means 15% of 25 is "greater than" 25% of 15.

Hope this helps.

Answer:

3⁻ⁿ⁺²

Step-by-step explanation:

we need to make both bases the same

9 can be written as 3²

[tex] \frac{3 {}^{n} }{3 {}^{2(n - 1)} } [/tex]

multiply 2(n-1) = 2n - 2

[tex] \frac{3 {}^{n} }{3 {}^{2n - 2} } [/tex]

I'll rewrite as 3ⁿ ÷ 3²ⁿ⁻²

subtract the exponents when dividing numbers with the same base

n - (2n-2) or n - 1(2n-2) imagine the 1 is there

remember that the whole of (2n-2) is being multiplied by -1, so expanding

n - 2n + 2 = -n + 2

final answer: 3⁻ⁿ⁺²

The break even point is the point where the cost and the revenue are equal

The break even point is at x = 50

The functions are given as:

C(x) = 30x + 500 --- cost function

R(x) = 40x ---- revenue function

At the break even, we have:

R(x) = C(x)

So, the equation becomes

40x = 30x + 500

Subtract 30x from both sides

10x = 500

Divide both sides by 10

x = 50

Hence, the break even point is at x = 50

Answer:  Choice C

(3 x 8) x 6 = 3 x (8 x 6)

=================================================

Explanation:

The associative property in general is

(a x b) x c = a x (b x c)

where the x stands for the multiplication symbol.

The a,b,c is in the same order for both sides, but grouped in slightly different ways with the parenthesis.

Plug in a = 3, b = 8, c = 6 to arrive at (3 x 8) x 6 = 3 x (8 x 6)

Answer:

47,1

Step-by-step explanation:

it is because when you multiply 3,14 by 15 you get your answer as 47,1 and it is a decimal

Using Multiplication, Jada need 47.1 feet of protective material around the rim of the pool.

Multiplication is the "method of finding product of two or more numbers".

According to the question,

A circular swimming pool has a diameter of 15 feet.

In order to find how many feet of protective material jada need:

Formula for area of circle = πr²  where 'r' is the radius of the circle.

Diameter = r²

= (3.14) (15)   [π = .14]

= 47.1

Hence, Jada need 47.1 feet of protective material around the rim of the pool.

Step-by-step explanation:

Perhaps simplest to explain is the use of a common denominator: 40.

  [tex]5 : 8 = (5\cdot5):(8\cdot5)=25:40\\\\7:10=(7\cdot4):(10\codt4)=28:40\\\\25:40 < 28:40\quad\leftrightarrow\quad\boxed{5:8 < 7:10}[/tex]

Other ways you can do this comparison are ...

  Multiply by 8·10 = 80, the product of the denominators:

     5·10 = 50 < 7·8 = 56

Answer:

[A]. a + 2(a – 3) = 15

Step-by-step explanation:

To See which equation is true for the value a = 7 Solve all of it.

Start with [A]

[A] a + 2(a – 3) = 15

7+2(7-3)=15

Hence,this is True.

Next ,[B]

[B] 4a-4(14-a)=24

4(7)-4(24-7)= -40

Hence, this is False.

Then, we have [C]

[C] 2a + 47 = 105

2(7) + 47 =61

Hence, this is False.

Now, We have [D]

[D] 3a+2(a-3)=34

3(7)+2(7-3)=29
Hence, this is False.

Lastly, We have [E]

[E] 4a-2a=18

4(7)-2(7)=14

Hence, this is False.

Thus, Correct Answer = [A].a + 2(a – 3) = 15
