Answer:
4 divided into 4000 is 1000 with no remainders
4/4000=1000
Answer- 4x-6
explain- i got it right
(i) Note that it is given to you that 3a + 2b = 9
You are trying to find the value of 9a + 6b. Find what is multiplied to both the variable a & b. Divide:
(9a + 6b)/(3a + 2b) = 3
Next, multiply 3 to the 9 on the other side of the equation:
3 x 9 = 27
27 is the value of 9a + 6b.
(ii) Note that it is given to you that 8x + 6y = 60
You are trying to find the value of 4x + 3y. Find what is multiplied to both the variable x & y. Divide:
(8x + 6y)/(4x + 3y) = 2
Next, divide 2 from the 60 on the other side of the equation:
60/2 = 30
30 is the value of 4x + 3y.

Answer:
y =-3 0 8 11 is a linear
Step-by-step explanation:
If you check it.
Ok, so I worked out the problem.
So for part a) you just multiply 8 by 25% then add the product to get the new perimeter.
Part B you Add all sides for the original square and the new square to get the perimeters of each then you divide the old square perimeter by the new square perimeter to get the percentage.
Part C you get the areas pf bother squares then divide the old square area by the new square area to get the percentage change.
If you have any questions, let me know.
