2x + 3(x +3) + (x + 6)
Volgvan

For this case we must simplify the following expression:

2x + 3 (x + 3) + (x + 6)

We apply distributive property to the terms within parentheses:

2x + 3x + 9 + x + 6 =

We add similar terms:

2x + 3x + x + 9 + 6 =\\6x + 15

Thus, the simplified expression is: 6x + 15

Answer:

6x + 15

In ΔWXY, the measure of ∠Y=90°, YX = 40, XW = 41, and WY = 9. What ratio represents the cosine of ∠W?
andreyandreev [35.5K]

Answer:

\cos(W) = \frac{9}{41}

Step-by-step explanation:

Given

\angle Y = 90^o

YX = 40; XW = 41; WY = 9

Required

Determine \cos(W)

The question is illustrated with the attached image.

So:

\cos(W) = \frac{Adajacent}{Hypotenuse}

\cos(W) = \frac{WY}{XW}

This gives:

\cos(W) = \frac{9}{41}
