It's a 1x2x3 box, aka parallelepiped. So we have 2 1x2 faces, 2 2x3 faces and 2 1x3 faces. We add them up:

A = 2(1 × 2 + 2 × 3 + 1 × 3) = 2(2+6+3) = 22

Answer: d. 22

Point S is between points R and T. Given that<br> RS ST and RS = 16, what is RT?

neonofarm [45]

Answer:

Step-by-step explanation:

Reason: point S is between points are and t

Meaning that Line RS≅ST

So if RS=16 then ST=16

To find RT we just add ST and RS

16+16=32

Therefore RT=32

hope this helps :)

The equation line l is given by the equation y= 7/4x+3. line m goes through the point ( –1,4) and is perpendicular to line l whi

mr_godi [17]

We determine line m as follows:

*First, by theorem we have the following:

$m_1=-\frac{1}{m_2}$

Here m1 & m2 are the slopes of two perpendicular lines. For all lines that are perpendicular that is true, so we calculate the slope of line m using the slope of the function given [Which has a slope of 7/4]:

$m_1=-\frac{1}{\frac{7}{4}}\Rightarrow m_1=-\frac{4}{7}$

So, the slope of line m is -4/7. Now, using this slope and the point (-1, 4) we replace in the following expression:

$y-y_1=m_1(x-x_1)$

Here x1, y1 & m1 are the x-component of the point, the y-component of the point, and the slope of the line respectively, so we replace and solve for y:

$y-4=-\frac{4}{7}(x-(-1))\Rightarrow y-4=-\frac{4}{7}x-\frac{4}{7}$ $\Rightarrow y=-\frac{4}{7}x+\frac{24}{7}$

And that last function of y is the line m.
