Start of by setting up the slope formula:
$\frac{y_2-y_1}{x_2-x_1} =slope$

We are given 2 coordinates and the slope
(-6,w)(-10,4)
slope:1/8

Label your coordinates:
(-6,w) and (-10,4)
x1,y1 x2-y2

Put these numbers into the formula
$\frac{4-w}{-10-(-6)} = \frac{1}{8}$

Simplify the current info given:
$\frac{4-w}{-4} = \frac{1}{8}$

Now you would be able to guess and check,

Final answer: w=9/2

Answer:

Dimensions : 1 by 1 by 2 feet,

Volume ⇒ 2 ft^3

Step-by-step explanation:

Here, I can only assume that this rectangular prism is assigned to have dimensions 1 foot by 1 foot by 2 feet;

I can tell that these types of boxes have height and width as the same lengths, so given that;

Dimensions : 1 by 1 by 2 feet,

Volume ⇒ 1 * 1 * 2 ( by definition ) ⇒ 2 ft^3

In other words, Volume ⇒ 2 ft^3

Factor 9x^2+66xy+121y^2

Korvikt [17]

Answer: (3x + 11y)^2

Demonstration:

The polynomial is a perfect square trinomial, because:

1) √ [9x^2] = 3x

2) √121y^2] = 11y

3) 66xy = 2 *(3x)(11y)

Then it is factored as a square binomial, being the factored expression:

[ 3x + 11y]^2

Now you can verify working backwar, i.e expanding the parenthesis.

Remember that the expansion of a square binomial is:

- square of the first term => (3x)^2 = 9x^2
- double product of first term times second term =>2 (3x)(11y) = 66xy
- square of the second term => (11y)^2 = 121y^2

=> [3x + 11y]^2 = 9x^2 + 66xy + 121y^2, which is the original polynomial.
