When the price of a certain commodity is p dollars per unit, the manufacture is willing to supply x hundred units, where 3 p^{2} − x^{2}= 12. How fast is the supply changing when the price is $4 per unit and is increasing at the rate of 87 cents per month?

x is greater than 5

step-by-step explanation:

2x+7 is greater than 17

    -7                           -7

2x is greater than 10

divide by 2 each side

x is greater than 5

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have

16.80 times .20= 3.36

step-by-step explanation:

answer: 1+1

step-by-step explanation: 1+1 is at least 2
