Step-by-step explanation:
the solutions are in the outside of the bigger circle, but inside of the smaller circle
Answer:
Step-by-step explanation:
4 and a half
Area of a square: s^2
Because we know the length of one side, we can multiply it by itself to find the area.
(3x - 6)(3x - 6)
9x^2 - 18x - 18x + 36
Combine like terms.
9x^2 - 36x + 36
<h3>The correct answer is A, or the first answer. </h3>
Answer:
Step-by-step explanation:
I guess the angles are supplementary, which means they have a sum of 180º.
11x - 15 + 5x - 13 = 180
16x -28 = 180
16x = 208
x = 13
Answer:
The length of BC = 12
Step-by-step explanation:
c^2 = a^2 + b^2
15^2 = 9^2 + b^2
225 = 81 + b^2
b^2 = 225 - 81
b^2 = 144
b = 12
The length of BC is 12
