The difference between the solution to the equation x² = a is 30.
x² = a
x = √a or x = -√a.
The difference between the solutions satisfies the condition
√a - (-√a) = 30
2√a = 30
√a = 15
a = 15² = 225
Check the answer.
When x = +√a,
x² = (√a)² = a Correct
When x = -√a,
x² = (-√a)² = a Correct
Answer: a = 225, and the answer checks out to be correct.
The <em><u>correct answer</u></em> is:
A) as the x-values go to positive infinity, the functions values go to negative infinity.
Explanation:
We can see in the graph that the right hand portion continues downward to negative infinity. The right hand side of the graph is "as x approaches positive infinity," since x continues to grow larger and larger. This means as x approaches positive infinity, the value of the function approaches negative infinity.
Answer:
Correct choice is 3rd choice
Step-by-step explanation:
Congruent circles must have congruent radii.
There are four circles with radii of 3 in, 4 in, 5 in and 3 in.
Hence, the first circle is congruent to the last circle, or circle A is congruent to the circle D.

The area of the shaded region is 46,77
Step-by-step explanation:
To determine the area of the shaded hexagon, we must first calculate te area of the whole shaded hexagon and minus that by the white little hexagon.
The formula to calculate the area of a hexagon is (3√3 s2)/ 2
(where s = one side of the hexagon)
if one side a the little white hexagon equals 6 ft;
3√3 6ft.2/2 = 18√3/2 = 9√3
now for the bigger hexagon where one side is 12 ft;
3√3 12 ft.2/2 = 72√3/2 = 36√3
now the area of the bigger one minus the area of the smaller one;
36√3 - 9√3 = 46,77
