(w_2)(w+7) multiply and simplify your answer

alexira [117]

If there is no number in between sets of numbers, it's going to be multiplication.
So (w+2) x (w+7)

w+2, well, evaluates into w+2.
w+7 is w+7.

We'll use the FOIL method for this.
FOIL stands for:

First
Outer
Inner
Last

Let's start with the first terms. Multiply them.
So: w * w.
Combine both w's, and you get $w^2$ .

Now multiply the outer terms.
w * 7 = 7w.

Then the inner terms. 2 and w.
2 x w = 2w.

So our current numbers are: $w^2$ , 7w, and 2w.
We can add 7w and 2w together.
7w + 2w = 9w.

Now multiply the last terms.
2 x 7 = 14.

So, this simplifies to $w^2+9w+14$
Hope this helped!

By trigonometric functions and law of cosines, the value of x associated with a missing angle in the geometric system is between 7.701 and 7.856.

<h3>How to find a missing variable associated to an angle by trigonometry</h3>

In this question we have a geometric system that includes a right triangle, whose missing angle is determined by the following trigonometric function:

sin (7 · x + 4) = 12/14

7 · x + 4 = sin⁻¹ (12/14)

7 · x + 4 ≈ 58.997°

7 · x = 54.997°

x ≈ 7.856

In addition, the geometric system also includes a obtuse-angle triangle and that angle can be also found by the law of the cosine:

7² = 8² + 6² - 2 · (8) · (6) · cos (7 · x + 4)

17/32 = cos (7 · x + 4)

7 · x + 4 = cos⁻¹ (17/32)

7 · x + 4 ≈ 57.910°

7 · x ≈ 53.910°

x ≈ 7.701

Hence, we conclude that the value of x associated with a missing angle in the geometric system is between 7.701 and 7.856.

Choose the solution to this inequality.

Mnenie [13.5K]

Answer:

A y < -1/2

Step-by-step explanation:

4/3 < -8/3 y

Multiply both sides by 3

3×4/3 < 3× -8/3 y

4 < - 8y

Divide both sides by -8

4/-8 > -8y/-8

The inequality sign changes by dividing by negative

-1/2 > y is same as y < -1/2

Therefore

y < -1/2
