All you have to do is add up all of the sides.
then once you have X, for part 2 all you need to do is replace X with 4 and then solve
The surface area of the rectangular prism is of 144 m².
<h3>What is a rectangular prism?</h3>
A rectangular prism is a solid that has three dimensions:
It's surface area is given by:
In this problem, the dimensions are: 
.
Hence:
![S = 2[6(6) + 6(3) + 6(3)] = 144](https://tex.z-dn.net/?f=S%20%3D%202%5B6%286%29%20%2B%206%283%29%20%2B%206%283%29%5D%20%3D%20144)
The surface area of the rectangular prism is of 144 m².

Hey there :)
27x² is what we are trying to factorise
When factorising, we do not add but we multiply
Jude factored : ( 20x )( 7x ) → This is wrong, since 20x × 7x = 140x²
Yasmin factored : ( 9 )( 3x² ) → This is right indeed as 9 × 3x² = 27x²
Yasmin is right

Answer:
40%
Step-by-step explanation:
Percent markup = new price - original price/original price
Do the subtraction first.
58.80 - 42.00 = 16.80
Now do the division
16.8/42 = 0.40
Change the decimal to a percent by moving the decimal two place to the right.
0.40 = 40%
