1. (2-3)(-8+2)+|-3+5|=?

2. -|-2-5+3|(5-2)=?

3. use two unit multipliers to convert 80ft into centimeters

4. use two unit multipliers to convert 12 square feet into square inches.

Answer 1

1) 8

2) -12

3) 80ft = 2438.4 centimetres

4) 12 square feet = 1728 square inches

Explanation:

1) ➟ (2−3)(−8+2)+|−3+5|

➟ (-1)(-6)+(2)

➟ 8

2) (−|−2−5+3|)(5−2)

=(−|−7+3|)(5−2)

=(−|−4|)(5−2)

=−4(5−2)

=(−4)(3)

=−12

3) 80ft = 2438.4 centimetres

4) 12 square feet = 1728 square inches
