1. the area of a square with side length x, where the side length is decreased by 3, the area is
multiplied by 2 and then 4 square units are added to the area.

Step-by-step explanation:

Let's follow what the problem asks us:

this is the formula for area:

since the side length is x, the initial area is:

The side is now , thus the area is:

we had the area , when we multiply by 2:

this is:

the quotient is 4x^2 - 27x + 167 with a remainder of -996

step-by-step explanation:

in synthetic division, use -6 as the divisor and use the coefficients {4, -3, 5, 6}:

-6     )   4     -3     5     6

                -24   162 -1002

          4   -27   167   -996

thus, the quotient is 4x^2 - 27x + 167 with a remainder of -996.

note:   your "4x°-3x+5x+6" is ambiguous / incomplete.   i had to assume that you meant '4x^3 - 3x^2 + 5x + 6."

sinn is the total amount of students now and m were the students before, you subtract them both (n-m) and divide that by m. then, since to get a percentage from a fraction you have to multiply by 100, your answer should look like this: n-m/m*100
