Describe the pattern and find the next two terms in the sequence.8, -4, 2, -1, ...

1 answer:

8 0

U have a geometric sequence and ur multiplying each number by -1/2 to get the next term.
8 * -1/2 = -8/2 = -4
-4 * -1/2 = -4/-2 = 2
2 * -1/2 = -2/2 = -1
-1 * -1/2 = 1/2
1/2 * -1/2 = -1/4

so ur next 2 terms are : 1/2 and - 1/4

The area of a rectangular knitted blanket is 10x squared minus 11x minus 6. What are the possible dimensions of the blanket? Us

Dmitrij [34]

Answer:

Dimensions of rectangle are $(5x+2)\:and\: (2x-3)\\$

Step-by-step explanation:

Area of rectangular knitted blanket = $10x^2-11x-6$

We need to find the dimensions of blanket.

If we need to find the dimensions, we need to find the factors of area.

Factoring: $10x^2-11x-6$

We will break the middle them -11x

Adding 4x-15x we get -11x

Multiplying 4x and -15x we get -60x^2 (Product of -6 and 10x^2)

Now, finding factors

$10x^2-11x-6\\10x^2+4x-15x-6\\2x(5+2)-3(5x+2)\\(5x+2)(2x-3)\\$

So, factors of $10x^2-11x-6\\$ are $(5x+2)(2x-3)\\$

So, dimensions of rectangle are $(5x+2)\:and\: (2x-3)\\$

(16x3 + 40x2 + 72) (2x + 6)

Volgvan

$(16x^3+40x^2+72)(2x+6)=32x^4+96x^3+80x^3+240x^2+144x+432=32x^4+176x^3+240x^2+144x+432$

In this case, you have to multiply each term of one parenthesis by each term in the second bracket. After receiving a number of factors need to be segregated and placed in the correct order.
