Answer:
A
Step-by-step explanation:
firstly you have to find the rate of change of the various price index in percentage.
A, From 106 to 112:
we find the difference 112-106 = 6
then the rate of change = 6/106 * 100 = 5.66%.
B ,From 112 to 118:
we find the difference 118-112 = 6
then the rate of change = 6/118 * 100 = 5.36%.
C ,From 118 to 124:
we find the difference 124-118 = 6
then the rate of change = 6/124 * 100 = 5.08%.
we can see that the price index with the greatest percentage is A.
So first we need to find what percent of the students walk to school.
50 + 35 = 85% don't walk leaving only 15% that walk to school,
To find the 15% percent that DO walk we multiply .15 by the total number of people.
.15 x 1640 = 246 people walk to school

Answer:
y = (2x + 3)(2x + 3) = (2x + 3)²
Step-by-step explanation:
We are given a quadratic function and we have to write it in factored form.
y = 9 + 12x + 4x²
y = 4x² + 12x + 9
We can break the mid-term in such a way that when they are multiplied, the factors give a product of 36x² and when added, they give a result of 12x, as show below:
y = 4x² + 6x + 6x + 9
Taking 2x common from the first two variables and 3 from the second two
y = 2x(2x + 3) + 3(2x + 3)
Taking 2x+3 common
y = (2x + 3)(2x + 3) = (2x + 3)²
