Katen [24]
Width = w
Length = 2w
Height = 4w
w \times 2w  = 384 \\  {2w}^{2}  = 384 \\  {w}^{2}  = 192 \\ w = 13.86cm
Width = 13.86cm

The Surface area of the triangular prism with the net shown below is 106 cm²

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more variables and numbers.

Surface area of the triangular prism = 2(0.5 * 5 * 3) + (7 * 3) + 2(7 * 5) = 106 cm²

The Surface area of the triangular prism with the net shown below is 106 cm²

Let s(t) = 36 − t. find the equation of the tangent line to s(t) when t = 0.
tatiyna
When t = 0 the point on the graph is (0,36). Your equation is just a line and always has the same tangent line so your equation is the same s = 36 - t.

How do i solve this?<br>13=x/4​
Alex17521 [72]

Answer:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :  

                    13-(x/4)=0  

Step by step solution :

Step  1  :

           x

Simplify   —

           4

Equation at the end of step  1  :

       x

 13 -  —  = 0  

       4

Step  2  :

Rewriting the whole as an Equivalent Fraction :

2.1   Subtracting a fraction from a whole  

Rewrite the whole as a fraction using  4  as the denominator :  

          13     13 • 4

    13 =  ——  =  ——————

          1        4    

Equivalent fraction : The fraction thus generated looks different but has the same value as the whole  

Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator  

Adding fractions that have a common denominator :

2.2       Adding up the two equivalent fractions  

Add the two equivalent fractions which now have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

13 • 4 - (x)     52 - x

————————————  =  ——————

     4             4    

Equation at the end of step  2  :

 52 - x

 ——————  = 0  

   4    

Step  3  :

When a fraction equals zero :

Now, to get rid of the denominator, Tiger multiple's both sides of the equation by the denominator. 3.1    When a fraction equals zero …

Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.

Here's how:

 52-x

 ———— • 4 = 0 • 4

  4  

Now, on the left hand side, the  4  cancels out the denominator, while, on the right hand side, zero times anything is still zero.

The equation now takes the shape :

  52-x  = 0  

Solving a Single Variable Equation :  

3.2      Solve  :    -x+52 = 0  

Subtract  52  from both sides of the equation :  

                     -x = -52  

Multiply both sides of the equation by (-1) :  x = 52

I WILL GIVE BRAINLIEST AND STARS AND A HEART!! PLEASE HELP!:
Lubov Fominskaja [6]

what's up? i'd say the scale factor is 25. although when you do 25x3.75 it's not exactly 94 (93.75), it does round up to it so i'd say that answer would be ok? and of course when we do 25x2 we get 50 feet wide

best of luck with your studies
