8equations with 2 addends that have a sum of 13

1) 2 + 11 = 13

2) 1 + 12 = 13

3) 3 + 10  = 13

4) 4 + 9 = 13

5) 5 + 8 = 13

6) 6 +  7 = 13

7)  21 + (-8) = 13

8)  20 + (-7) = 13

Step-by-step explanation:

Here we have to find 8 different numerical equations, when we 2 addends (numbers), we have to get the sum of 13.

1) 2 + 11 = 13

2) 1 + 12 = 13

3) 3 + 10  = 13

4) 4 + 9 = 13

5) 5 + 8 = 13

6) 6 +  7 = 13

7)  21 + (-8) = 13

8)  20 + (-7) = 13

answer rather than having to add and subtract the measurements of the semi-circle, notice that the semicircle to the left of ad is actually identical in area to the blank semicircle-shaped space to the left of bc. so if we transferred the red semicircle into the blank space, we would end up with a square of side length 24 cm. the area of a square is s^2 = 24^2 = 676 cm^2.

u also answered this so i think u would know but i am here to

put in or use mine
