Answer:

  • (x - 4)(x + 4)(x + 8)

Step-by-step explanation:

<u>Factorize the given expressions:</u>

  • x² - 16 = x² - 4² = (x - 4)(x + 4)
  • x² + 4x - 32 = x² + 8x - 4x - 32 = x(x + 8) - 4(x + 8) = (x - 4)(x + 8)

<u>The LCM is the product of all unique  factors of both expressions:</u>

  • (x - 4)(x + 4)(x + 8)

The least common multiple is the smallest expression that can be divided by both of the given expressions.

x^2 - 16 = (x - 4)(x + 4)

x^2 + 4x - 32 = (x + 8)(x - 4)

Both of the factored versions of the expressions have an (x - 4) in them. Thus, that will automatically be included in the LCM. Next, we have to include the (x + 4) and the (x + 8) in our LCM.

LCM = (x - 4)(x + 4)(x + 8)

Hope this helps! :)

-4(2-5b)=132<br> whats b?
Xelga [282]

Answer:

b = 7

Step-by-step explanation:

- 4(2 - 5b) = 132

- 4 × 2 - 4 × (- 5b) = 132

-8 + 20b = 132

20b = 132 + 8

20b = 140

b = 140/20

b = 7

Thus, The value of b is 7

A rectangle has a height of c^3+6c^2+2c and a width of c^2+1
Basile [38]

Answer:

A = c^5+6c^4+3c^3+6c^2+2c

Step-by-step explanation:

The dimensions of a rectangle are length and breadth/width

Here we are given height . Assuming it to be one of the side of the rectangle , we will do the further calculation

Hence one side is

side 1 = c^2+1

And the other side is

Side 2 = c^3+6c^2+2c

The area of rectangle = side 1 x side 2

A= (c^2+1) \times (c^3+6c^2+2c)

Distributing parenthesis

=c^2c^3+c^2\cdot \:6c^2+c^2\cdot \:2c+1\cdot \:c^3+1\cdot \:6c^2+1\cdot \:2c

=c^3c^2+6c^2c^2+2c^2c+1\cdot \:c^3+1\cdot \:6c^2+1\cdot \:2c

=c^5+6c^4+2c^3+c^3+6c^2+2c

adding similar terms

c^5+6c^4+3c^3+6c^2+2c

Hence Area is given by the above polynomial
