Here is your answer:
4x² + 28x + 49
4x² + 14x + 14x + 49
2x(2x) + 2x(7) + 7(2x) + 7(7)
2x(2x + 7) + 7(2x + 7)
(2x + 7)(2x + 7)
(2x + 7)²
= 28
Hope this helps!
Answer:
12
Step-by-step explanation:
We have 5 squared minus (3 squared plus 4). Convert this to mathematical expression:
- "5 squared" = 5²
- "minus" = -
- "3 squared" = 3²
- "plus 4" = + 4
Put it altogether:
5² - (3² + 4)
5² = 5 * 5 = 25 and 3² = 3 * 3 = 9, so:
25 - (9 + 4) = 25 - (13) = 12
The answer is thus 12.

Answer: Exterior
Step-by-step explanation:
Substitute the point (-2,4) into the equation of the circle 
.
Knowing that:
Then:
Therefore, as 
then the point is not on the circle.
If a point is in the interior of the circle , then:
Then the point (-2,4) is not in the interior of the circle.
If a point is in the exterior of the circle, then:
Then the point (-2,4) is in the exterior of the circle.
