Question

(−9+ 4,5) (-5 + 2,5); -156-(-6,5 + 3,63 0,3). .​

Answer 1

Ответ:

1)(−9+ 4,5) (-5 + 2,5)=(−9+ 4,5)*(-5 + 2,5)=-4,5*(-5+2,5)=-4,5*(-2,5)=11,25

2)-156(-6,5+3,63*0,3)=-156(-6,5+1,089)=-156*(-5,411)=844,116

Answer 2

It seems like you want to perform some basic arithmetic operations with the given numbers. Let's break it down step by step:

1. Calculate the first expression: (-9 + 4.5) * (-5 + 2.5)

   Start by solving the additions inside the parentheses: (-4.5) * (-2.5)

   Now, multiply the two negative numbers: 4.5 * 2.5 = 11.25

2. Calculate the second expression: -156 - (-6.5 + 3.63 * 0.3)

   Start by solving the addition inside the innermost parentheses: -156 - (-6.5 + 1.089)

   Now, solve the subtraction inside the outer parentheses: -156 + 6.5 - 1.089

   Finally, perform the remaining addition and subtraction: -149.589

So, the results are:

1. (-9 + 4.5) * (-5 + 2.5) = 11.25
2. -156 - (-6.5 + 3.63 * 0.3) = -149.589
