Whats the value of x and what is the length of side UW
solmaris [256]

We will calculate this by using ratios and because these two triangles are similar, which is very important.

Explanation:

We see that the FG = 9 corresponds to the VU = 21. Therefore, FH = 18 corresponds to the UW = x.

9 : 21 = 18 : x

x = (21*18)/9

x = 378/9

x = 42.

The correct answer is B. 42.

What is the equation of a line that passes through point R(3,7) and has a slope of 6?
djyliett [7]
The answer in slope intercept form is y = 6x-11

If you want the answer in standard form, then it would be 6x-y =11

notes:
* Slope intercept form is y = mx+b
* Standard form is Ax+By = C
=====================================

Explanation:

The given slope is m = 6
The line goes through (x,y) = (3,7)

Plug those three values into the equation below. Isolate b
y = mx+b
7 = 6*3+b
7 = 18+b
7-18 = 18+b-18 ... subtract 18 from both sides
-11 = b
b = -11

So because m = 6 and b = -11, this means y = mx+b turns into y = 6x-11

The answer in slope intercept form is y = 6x-11

To convert to standard form Ax+By = C, we just have to get all the x and y terms together on the same side. I'm going to move the y term to the right side and move the 11 to the left side

y = 6x-11
y+11 = 6x-11+11
y+11 = 6x
y+11-y = 6x-y
11 = 6x-y
6x-y = 11

The answer in standard form is 
6x-y = 11
which is a different way to write the same line

Solve the following question algebraically, show your work<br><br> 13 + w/7 &lt;-(fraction) = -18
evablogger [386]

Solve for w: by simplifying both sides of the equation, then isolating the variable.

w=-217

Work: 1.  Subtract 13 from both sides (w/7 = -18 - 13), 2.Simplify -18-13 to -31 (w/​7=-31), 3.Multiply both sides by 7 (w = -31 * 7), 4. Simplify 31*7 to 217 (w=-217)

How do you right a number in its prime factorization?
Whitepunk [10]
Please use "write" here, not "right." "write" is "right" here, if you get my drift.
"right" is wrong in this context.    ;)

Example:  Most of us would see immediately that 5 is a prime factor of 50.

Write 50 as 5 * 10.

10 is not prime; it can be factored into 5 and 2.

Thus, 50 written as the product of its prime factors is 5 * 5 * 2  (answer)
