factorise a³ - b³ + 4a-4b
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]a^3-b^3[/tex][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]4a-4b[/tex][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]

(7TH GRADE LEVEL) Read the instructions and answer questions 16-18
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?

How would you do this and how would you graph it on a number line
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.

The length of a rectangle is four times its width.
If the area of the rectangle is 144 ft, find its perimeter.
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

Let's solve your equation step-by-step.
7x+3+x+55=14x−5+x
Step 1: Simplify both sides of the equation.
7x+3+x+55=14x−5+x
7x+3+x+55=14x+−5+x
(7x+x)+(3+55)=(14x+x)+(−5)(Combine Like Terms)
8x+58=15x+−5
8x+58=15x−5
Step 2: Subtract 15x from both sides.
8x+58−15x=15x−5−15x
−7x+58=−5
Step 3: Subtract 58 from both sides.
−7x+58−58=−5−58
−7x=−63
Step 4: Divide both sides by -7.
−7x
−7
=
−63

a force of 10 newtons acts in a direction 75 above horizontal moving an object 15 meters from (0,0) to (15,0). What is the work done by the force?
a. 2.59 joules
b. 3.88 joules
c. 38.82 joules
d. 150.00 joules
Answer:
150 JoulesStep-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
