Answer:
The are infinite
Step-by-step explanation:
some are 1,-1
2,-2
3,-3
10000,-10000
Let the amount that the boys sold be x, the amount that girls sold will be 3x. The total will be given by:
x+3x=180
4x=180
solving for x we get:
x=180/4
x=45
Thus, boys sold $45, the girls provided 45*3=$135
Area of a square=side²
Data:
area=1230 mm²
Therefore:
side²=1230 mm²
side=√1230 mm²≈35.07 mm
Answer: the length of the side would be 35.07 mm
Yes not sure though but I want to say yes
