Step-by-step explanation:
Given
n = 5
1. 9n - 9
= 9 * 5 - 9
= 45 - 9
= 36
2 . (3n + 5n) 10
= ( 3 * 5 + 5* 5)10
= 40* 10
= 400
3 . 12 * n/2
= 12 * 5 / 2
= 6 * 5
= 30

To find the weight of 1 load of stone, divide 2/3 by 4.
To divide fractions, use keep change flip.
Keep the first fraction the same, change the division sign into a multiplication sign, and flip the second fraction.

Answer:
b=2r+4
Step-by-step explanation:
I don't think that you can do this using only one variable because there are two unknown amounts. Blue (b) is Red (r) multiplied by 2 plus 4 more, so the expression is b=2r+4.
A=16x²-8x+1
16x²-8x+1=l²
(16x²-4x)-(4x+1)=l²
4x(4x-1)-1(4x-1)=l²
x=1/4 or 1
Therefore
since x=1/4
l²=1/4=>l=>√(1/4)
l=1/2
since x=1
l²=1=>l=>√1
l=1
Therefore the length of each sides
1 or 1/2
