We sketch the two similar shapes and they are as shown in the attachment. We want to write corresponding side's length in ratio
Writing the two ratio as fraction gives
Cross multipliying gives
Can you please tell me what the first question says? i can read it, its too dark
Since it is a cube, all sides lengths are the same.
Surface area = 2lw+2lw+2hw
if you substitute all the sides for 13 you get
2(169) three times
so you multiply and get 338 three times so you do 338x3 which is 1014 cm
its messy to explain so i attached a photo
Answer:
2x-7
Step-by-step explanation:
To find the total price, we use this equation:
42 + 0.039(42)
We can make it simpler:
1.039(42)
Multiply:
43.638
Because we're rounding
The total price is $43.64
