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.

The question stated that the difference of the square of a number and three times the sum of the number and 7 (x^2-3 (x+7))is more than the product of that number and 15 (15x)

So x^2- 3(x+7)>15(x)= x^2 -3x +21>15x

answer

explanation

the area of a circle is calculated using the formula

or

we can use any of the above formulae to calculate the required. preferably, let us use the latter since the diameter is

we substitute the diameter into the formula to get:

this is the exact value for the area of the circle.

the correct answer is a
