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

25.2

step-by-step explanation:

2+4x6-8/10= 25.2

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°

what level of math? also i don't need to be paid if i can you.
