A loud clap of thunder is measured at a noise level of 120 decibels (the unit for measuring sound). The next
two thunderclaps register a decrease of 20% followed
by a 25% increase in noise level. How loud, in decibels,
is the third thunderclap?

[15 points]find the least common multiple of the expressions: 1. 3x^2, 6x - 18 2. 5x, 5x(x +2) 3. x^2 - 9, x + 3 4. x^2 - 3x - 10, x + 2 explain if possible

What is the solution to the division problem below x3+x2-11x+4/x+4

Will mark determine whether the conjecture is true or false. give a counterexample for any false conjecture. given: points r, s, and t conjecture: r, s, and t are coplanar. a) false; the points do not have to be in a straight line. b) true c) false; the points to not have to form right angles. d) false; one point may not be between the other two.
