The answer is none. Since you have to add your a's first, your left with 0 meaning that there is no more a's meaning that you have no solution. Hope this helps!
that's the simplification mod
Answer:
C (circumference) =2×π×r
we've got a 30-60-90 triangle
which means 9=d√3, d=5.19 exact inches
or ≈5.20 inches
d=2r, r=5.20÷2≈2.60 inches
C=2×3.14×2.60≈16.328
Answer:
The answer is B
the shaded part is below which signifies a less than sign
so you can cross out options A and C
now make y=0
for option B, it will give √Xless than or equal to √4
for option D, it will give √4 less than or equal to √x
to bring √x to the other side, the inequality sign will change to greater than
Therefore the answer is B
