Answer:
1,2,3
Step-by-step explanation:
3 and below ×2 are less than or equal to 6.
A circumscribed angle is that which is formed by the intersection of the two tangent lines in a circle. With this, we can conclude that segments AC and AB are tangent to circle O. The tangent lines forms a right angle with the radius of the circle drawn from the center of the circle to the tangent point.
By the explanation above, we can say that angles C and B are equal to 90° and that triangle ACO and triangle ABO are congruent. Which means that segment AC is equal to segment AB. Thus, the length of AB is also 4.
<em>Answer: 4 units</em>
Answer:
66
Step-by-step explanation:
![\sqrt{324} + 6 \sqrt{64}\\\\=\sqrt{18^2} +6 \sqrt{8^2}\\\\=18+6(8)\\\\=18+48\\\\=66](https://tex.z-dn.net/?f=%5Csqrt%7B324%7D%20%2B%206%20%5Csqrt%7B64%7D%5C%5C%5C%5C%3D%5Csqrt%7B18%5E2%7D%20%2B6%20%5Csqrt%7B8%5E2%7D%5C%5C%5C%5C%3D18%2B6%288%29%5C%5C%5C%5C%3D18%2B48%5C%5C%5C%5C%3D66)
Answer:
5. A) two solutions
6. one solution
Step-by-step explanation:
5. A graph shows the curve has two x-intercepts, so two solutions. You can also figure this by looking at the discriminant:
b^2 -4ac = (7)^2 -4(-4)(8) . . . . a positive number
When the discriminant is positive, there are two real solutions.

6. The equation factors as ...
0 = 3(x +3)^2
This will have one real solution at x=-3.
Remark
The five is after the decimal point. The 10 in that form is tenths. It represents a number in the denominator. So you would write it as 5/10 and say it as 5 tenths.
The answer is D.
