How do I find a surface area of a prism

Depends on the prism!

Here are the basic ones:

SA of rectangular prism = 2lw + 2wh + 2lh OR 2(lw+wh+lh)

SA of triangular prism = 2*area of base + perimeter of base*height

Answer:

20 votes

Step-by-step explanation:

You start with the percents: You always start with 100%

100-5=95

Then you multiply

95 x 4

4 is how many votes he received the 2nd time

95 x 4= 380

Then you subtract

380-360= 20

Your Welcome :)

Use slope-intercept form, y = mx + b, to find the value for the y-intercept (b) of a line that has a slope of 6 and passes throu

stiks02 [169]

Answer:

-23, $y=6x-23$

Step-by-step explanation:

We need slope intercept form but do not have the needed information. We will gather this information by using point slope form. The point-slope formula is $y -y_{1} =m(x -x_{1})$ where we substitute a point (x,y) for $(x_{1},y_{1})$ .

We have slope represented as m=6 and (3, -5). We input m and $x_{1} =3\\y_{1}=-5$ .

$y-(-5)=6(x-3)\\y+5=6(x-3)$

We now simplify the parenthesis and solve for y to have slope intercept form.

$y+5=6(x-3)\\y+5=6x-18\\y+5-5=6x-18-5\\y=6x-23$

The y-intercept is b of slope intercept form y=mx+b. Here b=-23.
