Answer:
b^2 - 6b - 55
Step-by-step explanation:
(b + 5)(b - 11)
Use FOIL

F: b * b = b^2
O: b * -11 = -11b
I: 5 * b = 5b
L: 5 * -11 = -55
b^2 - 11b + 5b - 55
Combine like terms
-11b + 5b = -6b
b^2 - 6b - 55
Step-by-step explanation:
distance between (12.-7) and (-3, -7)
=12+3
=15 units
The problem ask to calculate the slope of the line tangent to a circle O at point A if the radius of the circle is 2.5. So based on the problem the tangent line formed a right angle so it means that the slope is also 2.5 and the answer is letter B. 2.5
Answer:-16
Step-by-step explanation:
