Answer 2

Let's solve each expression step by step:

A) -59 * (-11) = ? To multiply two negative numbers, the result is positive. So, -59 * (-11) = 59 * 11 = 649

6. -5.4 * 0.9 = ? Simply multiply these two numbers: -5.4 * 0.9 = -4.86

B) -5(-r) - 2.8 * (-3) * (-10) = ? First, simplify the expression: -5(-r) = 5r -2.8 * (-3) * (-10) = 84 Now, combine the two terms: 5r + 84

A) (-0.4)^2 = ? To square a number, you multiply it by itself: (-0.4)^2 = (-0.4) * (-0.4) = 0.16
