Mathematics

lora16 [44]3 years ago
3 0

Answer:

(11b^2 + 7) (11b^2 - 7)

Explanation:

Since both terms are perfect squares, factor using the difference of squares formula,  a^2 - b^2 = (a + b) (a - b) where a = 121b^4 and b = 49

Determine if line AB is tangent to the circle. Type
adoni [48]

Answer:

If AB is a tangent to the circle, the triangle ABO is right angled, as the angle where a tangent meets the circumference is always 90 degrees.

We also know that Pythogoras' theorem only holds for right angled triangles.

The hypotenuse is 12 + 8 as 12 is the radius so is 20.

16^2+12^2 = 256 + 144 = 400 = 20^2 so AB must be tangent.
