Answer:

[tex]a^3-b^3+4a-4b:\:\left(a-b\right)\left(a^2+ab+b^2+4\right)[/tex]

Step-by-step explanation:

Given the expression

[tex]a^3-b^3+4a-4b[/tex]

solving the expression

[tex]a^3-b^3+4a-4b[/tex]

as

[tex]\mathrm{Apply\:Difference\:of\:Cubes\:Formula:\:}x^3-y^3=\left(x-y\right)\left(x^2+xy+y^2\right)[/tex]

[tex]a^3-b^3=\left(a-b\right)\left(a^2+ab+b^2\right)[/tex]

also

[tex]\mathrm{Factor\:out\:common\:term\:}4[/tex]

[tex]=4\left(a-b\right)[/tex]

so the expression becomes

[tex]=\left(a-b\right)\left(a^2+ab+b^2\right)+4\left(a-b\right)[/tex]

[tex]\mathrm{Factor\:out\:common\:term\:}\left(a-b\right)[/tex]

[tex]=\left(a-b\right)\left(a^2+ab+b^2+4\right)[/tex]

Therefore,

[tex]a^3-b^3+4a-4b:\:\left(a-b\right)\left(a^2+ab+b^2+4\right)[/tex]

Answer:

  3.347 N

Step-by-step explanation:

The vertical component of the dragging force is (120 N)/√2, so the net downward force is the difference between that due to gravity and the upward component of the dragging force.

  (9.8 m/s²)(9 kg) -(120 N)/√2 = 3.347 N

The normal force acting on the log is 3.347 N.

Answer: 12+8x

Step-by-step explanation:

1) 4(3+2x)- Distribute the 4

4x3+4x2x t get 12+8x

Answer:

Step-by-step explanation:

Step one:

Given data

Force F= 10N

the distance is described by the coordinate =  (0,0) to (15,0)

hence the distance = 15m in the x-direction.

Step two:

Required is the work done

we know that work done is expressed as

Wd= Force* Distance

Wd= 10*15

Wd= 150 Joules

Answer:

38.82

Step-by-step explanation:

Answer:

k=-5,5

Step-by-step explanation:

first you calculate (by switching  the -6 to the other side)

|k|<-1+6

second you add the -1+6 and get |k|<5

the other part will be that the |k| will turn to - negative.

now you will have -k<5 then not you have to take the negative of -k to only have, (k<-5), k equalling to -5.

But remeber you always flip the < to > when you have the greater-to-equal sign or less-to-equal sign.

When looking at the y part of the answer, you can see it goes up by three and that it is missing a point. This means that if the equation is linear, it goes up by one. Hope that's right!!

Answer:

$16.60

Step-by-step explanation:

4 x 0.85 = $3.40

20 - 3.40 = 16.6

Dave should get back $16.60 in change.

Answer:

$16.6 dollars back

Step-by-step explanation:

The answer is $16.6 because 0.85 times 4 is 3.4 and 20 minus 3.4 is 16.6

Answer:

Equations

Step-by-step explanation:

16:

7 · (-3) = -21

-3 · 7 = -21

-21 ÷ 7 = -3

-21 ÷ (-3) = 7

17:

-4 · (-5) = 20

-5 · (-4) = 20

20 ÷ (-4) = -5

20 ÷ (-5) = -4

18:

1.5 · (-3) = -4.5

-3 · 1.5 = -4.5

-4.5 ÷ 1.5 = -3

-4.5 ÷ (-3) = 1.5

This is 7th grade?

Hope I helped :)

Answer:

16. 7 x -3= -21

    -3 x 7= -21

    -21/-3=7

    -21/7=3

17. -4 x -5= 20

    -5 x -4= 20

    20/-4=-5

    20/-5=-4

18. 1.5 x -3= -4.5

   -3 x 1.5=-4.5

   -4.5/-3=1.5

   -4.5/1.5=-3

x=0.571428571

Step-by-step explanation:

4-7x=0

x=0.571428571

Answer:

Step-by-step explanation:

x = 2.591

or

x = -0.257

Answer:

0

Step-by-step explanation:

You can’t divided 0 by 0 so it’s 0

Answer:

y = mx + c

since m = 0

c = 9

Answer: 60

suppose: the width of a rectangle is x (x > 0)

⇒ The length of a rectangle is 4x

because  the area of the rectangle is 144 ft

=> 4x.x = 144

⇔ x² = 144/4 = 36

⇒ x = 6

with x = 6 ⇒ The length of a rectangle is 4.6 = 24

the perimeter of the rectangle is (6 + 24).2 = 60

Step-by-step explanation:

Answer:

4x=x+18x=

We move all terms to the left:

4x-(x+18x)=0

We add all the numbers together, and all the variables

4x-(+19x)=0

We get rid of parentheses

4x-19x=0

We add all the numbers together, and all the variables

-15x=0

x=0/-15

x=0

Answer:

x = 35 degrees

Step-by-step explanation:

All angles in a triangle add up to 180 degrees.

Therefore, 48 + 97 + x = 180

Solve for x.

Thus, x = 180 - 48 - 97.

x = 35 degrees

Answer: Subtract 2x from both sides of the equation. Multiply each term in −y=−3−2x - y = - 3 - 2 x by −1 - 1 . Multiply (−y)⋅−1 ( - y ) ⋅ - 1 .

Answer:

y= -3

Step-by-step explanation:

to find y- intercept, substitute x= 0

2 x 0 - y = 3

y= -3

Answer:

slope = 0

Step-by-step explanation:

(-3, 2) and (6, 2)

slope = (y1 - y2)/(x1 - x2)

remember, either x or y can be used but you have to be consistent

slope = (2-2)/(-3-6)

slope = 0/(-9)

slope = 0

Answer: no slope or 0

Step-by-step explanation:

The y-coordinates are the same for both points but the x coordinates are different. This signals a no-slope line, or a line where the slope is 0. Even if we apply the formula, which is [tex]\frac{y_2-y_1}{x_2-x_1}[/tex], it still ends up with 0.
