Step-by-step explanation:
.....because the coefficient of x is 2, a positive number.

Here's the solution ~
Area of floor is ;


Area covered by rug is ;

So, the percentage of floor covered by rug is ~




90 is the LCM of 30 and 45
Remember
√(mn)=(√m)(√n)
and
√-1=i
√-25=(√-1)(√25)=(i)(5)
aswer is +/-5i
We can use the Sine Law:a / sin A = b / sin B2 / sin 75° = 3 / sin B2 / 0.966 = 3 / sin B ( after that we will cross multiply )
2 sin B = 3 · 0.9662 sin B = 2.898sin B = 2.898 : 2sin B = 1.499 > 1 ( it is not possible )Answer: A ) No triangles can be formed.
