27 because the square root of 81 is 9 and 9 times 3 is 27.
Answer:
4: 19
5: 20
6: 21
Step-by-step explanation:
So it says to use the equation t=q+15, so 4+15 is 19, 5+15=20, 6+15=21
That would be -12852/125 I believe
Answer: C
Step-by-step explanation:
πr^2 is how you find area
r=1/2(d)
r=1/2(12)
r=6
6^2=36
36π
Answer:
C
Step-by-step explanation:
first of all, the correct factorization is
y = (x - 3)(x + 6)
because when we do the multiplication
y = x² + 6x - 3x - 18 = x² + 3x - 18
and then, the factorization tends us also directly the zero points, because y is only 0, when one of the factors is 0.
so, either x-3 or x+6 has to be 0 to make the whole expression 0.
and that is only for x=3 or x=-6
