27 and 36
12 is too short to be multiplied by 9, 21 can be multiplied by 3 but not 9 again, 3 can’t go into 45. Which leaves 27 and 36. 3 times 9 equals 27. 3 times 12 equals 36, 9 times 4 equals 36.

Multiply:

Step-by-step explanation:
a. 7143 - 6997 = 146 units
b. First 100 units: 24p/unit
Remaining units: 16p/unit
100x24p = 2400p
46x16p = 736p
Cost: 3136p
Answer: x = 44
Step-by-step explanation:
The exterior angles of a polygon add to 360 degrees so:
- (3x+4)+(3x+4)+29+34+25=360 [forming equation]
- 6x+96=360 [combine like terms]
- 6x=264 [subtract 96 from both sides]
- x = 44 [divide both sides by 6]
