Answer

-8.25

Work Step by Step

To simplify the expression you must use order of operations. In the equation: -3 x 5 +(-9) / 4 + 3^2 The first thing we do is simplify the exponent, resulting in: -3 x 5 +(-9) / 4 +9 *Multiply -3 x 5 to get: -15+(-9)/4+9 *Divide -9 by 4 to get: -15-2.25+9 *Add the two negative numbers -15 and -2.25 to get: -17.25+9 *Add 9 and -17.25 together to get the solution: -8.25
