At the beach the cost for renting a surf board is 39 dollars for 3 hrs. At this rate that is the charge for 8 hrs.

The answer vary but let use 9 and 8.

Step-by-step explanation:

First, let write this equation down.

[tex] {x}^{2} + 6x + c[/tex]

In order to factor this expression, we must think of two numbers that can add to 6, but Also multiply to C. This number vary but let use two potential scenarios

Let use 3 and 3 since 3+3=6 to find C let multiply 3 and 3.

3x3=9.

So one value of C could be 9.

This expression factor equal

[tex](x + 3) {}^{2} [/tex]

Let use another one.

Since 2 and 4 add to 6. Let multiply 2 and 4 to find C.

[tex]2 \times 4 = 8[/tex]

So c=8

Thus expression factor equal

[tex](x + 2)(x + 4)[/tex]

Answer:

The answer i got is 192

Step-by-step explanation:

the largest numbers shown is 8,6 and 4. When you multiply all three of them you get 192

Answer:

280

Step-by-step explanation:

Through trial and error, one can figure out that the answer is 280. Now, you might first try to go 8 * 6 * 4, which equals 192. However, if you get the product of two negative numbers, it becomes a positive, which we can use. Using the numbers -7, -5 (which cancel out each other making the product positive), and 8, the product of all of them is 280. The largest product that Khushali can make is 280.

8 * 6 * 4 = 192

(-7) * (-5) * 8 = 35 * 8 = 280

Answer:

5b + 12c

Step-by-step explanation:

-5a +5 a = 0

12b-7b = 5b

12c= 12c

therefore you have the expression 5b+12c

Answer:

Step-by-step explanation:

if we have

-0.3x-30=60

-0.3x=60+30

-0.3x=90

x=90/-0.3

x=-300

Answer:

Isolate the variable by dividing each side by factors that don't contain the variable.

x = -300

Step-by-step explanation:

9514 1404 393

Answer:

  90°

Step-by-step explanation:

Any corner angle in a rectangle is 90°. Rotating the figure does not change that. Angle O' = 90°.

_____

Additional comment

No rigid transformation (translation, rotation, reflection) changes any angles. Nor does uniform dilation (the kind we usually study). Hence any rectangle that is translated, rotated, reflected, or dilated will still have all angles measuring 90°.

Answer: 2880 flowers

Step-by-step explanation:

Since 648 flowers were arranged in 27 large vases, with the same number in each vase, this means that each vase will contain 24 flowers

= 648/27

= 24 flowers

Therefore, the number of flowers needed to fill 120 vases will be:

= 24 × 120

= 2880 flowers

Answer:

Steve can buy 25 songs with his gift card.

Step-by-step explanation:

Money with Steve = $ 100

Money per song = $ 3.99

No. of songs Steve can buy =?

No. of songs Steve can buy = Money with Steve ÷ Money per song

No. of songs Steve can buy = $100 ÷ $3.99 (round off 3.99 to 4)

= 100 ÷ 4

= 25 songs.

Step-by-step explanation:

= -6m+b

2= -2m+b

2= -4m

m= -0.5 = -1/2

4= -6m+b

b= 4+6(-0.5)= 4-3=1

y=mx+b

y= -1/2 x + 1

Answer:

-24

Step-by-step explanation:

Since only one of the factors has a negative sign, the product will be negative.

4 · (-6) = -24

Answer:

-24

Step-by-step explanation:

4×(-6)

Remove parenthesis

-4 x 6

= -24

Extra

Its basically the same thing as 4 x 6 (which is 24) the only difference here is that the 4 is a negative.

POSITIVE FORM             NEGATIVE FORM

4 x 6 = 24                           -4 x 6 = -24

6 x 4 = 24                            -6 x 4 = -24

Answer:

[tex]x^4 - 81 = (x - 3)(x+3)(x^2 + 9)[/tex]

Step-by-step explanation:

Given

[tex]x^4 - 81[/tex]

Required

Write an equivalent expression

Express 81 as 9^2

[tex]x^4 - 81 = x^4 - 9^2[/tex]

Express x^4 as (x^2)^2

[tex]x^4 - 81 = (x^2)^2 - 9^2[/tex]

Apply difference of two squares:

[tex]x^4 - 81 = (x^2 - 9)(x^2 + 9)[/tex]

Express 9 as 3^2

[tex]x^4 - 81 = (x^2 - 3^2)(x^2 + 9)[/tex]

Apply difference of two squares

[tex]x^4 - 81 = (x - 3)(x+3)(x^2 + 9)[/tex]

Hence, an equivalent expression is: [tex](x - 3)(x+3)(x^2 + 9)[/tex]

Step-by-step explanation:  Chemical signal is the type of communication which coordinates actions between neighboring cells . This ability originated in single cells organisms and was essential for the evolution of multicellular organisms because after a cell receives a message, it is transferred across the plasma membrane and changes are brought about within the cell in response to this message.

Step-by-step explanation:

Answer:

side length of the smaller room = 5 m

Side length of the larger room = 8 m

Step-by-step explanation:

Total area of two square room = 89 m²

Area of a square = side²

Let

x = side of the smaller square

x + 3 = side of the longer square

Total area = area of room A + Area of room B

89 = x² + (x + 3)²

89 = x² + x² + 6x + 9

89 - 9 = 2x² + 6x

2x² + 6x = 80

2x² + 6x - 80 = 0

Divide through by 2

x² + 3x - 40 = 0

Solve quadratic equation using factorization method

x² + 8x - 5x - 40 = 0

x(x + 8) -5(x + 8) = 0

(x - 5) (x + 8) = 0

(x - 5) = 0 (x + 8) = 0

x = 5 x = -8

The side length of a square room can not be a negative value

Therefore, side length of the smaller room = 5 m

Side length of the larger room = 5 + 3

= 8 m
