(A) 1.8
The difference is 18, 13 is bc the tenth term so divide 18 by 10 to get 1.8
Answer:
(−3x−9)+(4x+8)
=(−3x+4x)+(−9+8)
=x−1
Step-by-step explanation:
Answer: is this correct
Step-by-step explanation:
Answer:
A = 176.7 units²
Step-by-step explanation:
Put the hint to use. Do these side lengths reflect the Pythagorean Theorem?
9^2 + 12^2 = 15^2?
81 + 144 = 225? YES
Therefore, this is a right triangle, and the diameter is 15 units.
Thus, the radius is 15/2 units, and the area is A = πr², or
A = π(15/2 units)² = (225/4)π units². Using 3.14 for π, we get:
A = 176.7 units²
