Answer:

1) C

2) D

3) The answer is not in the choices given.

4) The answer is not in the choices given.

5) D

6) C

7) D

8) There's no rectangle.

9) A

10) A

Step-by-step explanation:

1) To add integers with different signs, keep the sign of the number with the largest absolute value and subtract the smallest absolute value from the largest.

2) 29,028 feet + 1,312 feet = 30,340 feet(ft)

3) 7 + (-3) + (- 12)

= 7 - 3 - 12

= 7 - 15

= - 8 (Answer is not in the choices)

4) 3 + (-7)

= 3 - 7

= - 4 (Answer is not in the choices)

5) A. -7 + 3 = -4 (A negative sum) , B. -7 + + 3 = -4 (A negative sum) , C. + 7 + -8 = -1 (A negative sum) , D. 7 + + 8 = +15 (A positive sum)

6) -6 + -5 = -11

7) +20 + +5 = +25

8) The values were not specified.

9) -32 + -18 = -50

10) +8 + +5 = +13

Hope this helps.
