The difference of the square of a number and three times the sum of the number and 7 is more than the product of that number and 15.

select the inequality that can be used to determine the unknown number.

a.
x2 - 3x + 21 > 15 + x
b.
x2 + 3x ≥ 15 + x
c.
x2 - 3x + 7 ≥ 15x
d.
x2 - 3x - 21 > 15x

c hope this helps btw im

Step-by-step explanation:

square of a number =x²

3 times the sum of the number and 7= 3(x+7)

their differences=x²-3x-21

more than product of number and 15= >15x

so x²-3x-21>15x

13

step-by-step explanation:

distance formula is d=√(x2-x1)^2   +   (y2-y1)^2

i think is g(1)=-1.

hope that i can
