factorise a³ - b³ + 4a-4b

Answers

Answer 1

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]

Tyler incorrectly says that the constant term of (x + 4)(x - 4) is zero.
a. What is the correct constant term?
b. What is Tyler's mistake? Explain your reasoning.

Answers

Answer:

a. -16 is the constant

b.if you expand the equation it would be x^2-16, and the constant is -16

Solving the expression (x + 4)(x - 4) ; the constant term in the expression is - 16 and not 0

To solve, we need to expand the expression : (x+4)(x-4)

Expanding the expression :

(x + 4)(x - 4)

Opening the bracket :

x² - 4x + 4x - 16

x² - 16

The constant term in the expression, is - 16 as it is the value without a variable.

Therefore, Tyler's mistake is incorrectly stating that the constant value is 0 instead of - 16

General admission to Paul’s Pumpkin Patch is $8.00. For children to ride the various rides, they must use tickets that cost $1.00 each. The number of tickets needed for each ride varies. The function for this situation is P(x) = x + 8, where P(x) represents total cost as a function of the number of tickets, x. What is the domain for visiting and riding rides at Paul’s Pumpkin Patch?
A. P(x) ≥ $8.00
B. x is all real numbers
C. x ≥ 0, where x is non-negative
D. x ≥ 0, x is an integer

Answers

Given:

Total cost P(x) as a function of the number of tickets, x is

[tex]P(x)=x+8[/tex]

To find:

The domain for visiting and riding rides at Paul’s Pumpkin Patch.

Solution:

Domain is the set of input values.

Here, domain is x and it represents the number of tickets.

We know that, number of tickets cannot be negative or decimal or fraction vales. So, x must be non-negative and integer value.

Domain = x ≥ 0, x is an integer

Therefore, the correct option is D.

Given h(x) = 4x – 5, solve for x when h(x) = 7.

Answers

Answer: x = 3 when  h(x) = 7.

Step-by-step explanation:

h(x) = 4x -5      To solve for x when h(x) = 7,  you will set the expression 4x -5 equals 7 to solve for x.

4x -5 = 7    Add 5 to both sides

   +5   +5

4x = 12       Divide both sides by 4.

x= 3

Answers

Answer:

[tex] b = 5.5 [/tex]

[tex] c = 11.2 [/tex]

Step-by-step explanation:

Given:

A = 96°

B = 25°

C = 59°

a = 13

Required:

b and c

SOLUTION:

Use Sine Rule to find the measure of a and b, respectively.

✍️Thus, to find b, use,

[tex] \frac{a}{sin(A)} = \frac{b}{sin(B)} [/tex]

Plug in the values

[tex] \frac{13}{sin(96)} = \frac{b}{sin(25)} [/tex]

Multiply both sides by sin(25)

[tex] \frac{13}{sin(96)} \times sin(25) = \frac{b}{sin(25)} \times sin(25) [/tex]

[tex] \frac{13 \times sin(25)}{sin(96)} = b [/tex]

[tex] b = 5.5 [/tex] (nearest tenth)

✍️To find c, use,

[tex] \frac{a}{sin(A)} = \frac{c}{sin(C)} [/tex]

Plug in the values

[tex] \frac{13}{sin(96)} = \frac{c}{sin(59)} [/tex]

Multiply both sides by sin(59)

[tex] \frac{13}{sin(96)} \times sin(59) = \frac{c}{sin(25)} \times sin(59) [/tex]

[tex] \frac{13 \times sin(59)}{sin(96)} = c [/tex]

[tex] c = 11.2 [/tex] (nearest tenth)

Answers

Answer:

8.75 feet

Step-by-step explanation:

Use the area formula, A = lw, where l is the length and w is the width

Plug in the area and length, and solve for w:

A = lw

140 = 16w

8.75 = w

So, the width is 8.75 feet

Answer:

8.75 ft

Step-by-step explanation:

Use the area formula, A = lw, where l is the length and w is the width

Plug in the area and length, and solve for w:

A = lw

140 = 16w

8.75 = w

So, the width is 8.75 feet

Answer:

Step-by-step explanation:

log(5x+10)-log(4x+12)=1-2log(3)

log(5x+10/4x+12)=1-2log(3)

log(5x+10/4x+12)=log(10)+log(3^-2)

log(5x+10/4x+12)=log(10×3^-2)

log(5x+10/4x+12)=log(10×1/9)

log(5x+10/4x+12)=log(10/9)

f(x) = 3x + 13(17x-7)

f(x) = 3 × 4 + 13(17 × 4 - 7)

f(x) = 12 + 13(68 - 7)

f(x) = 12 + 13 × 68 - 13 × 7
