Answer:
32 degrees
Step-by-step explanation:
Because the triangle is isosceles, 2 of its angles must equal each other:
15x - 31 = 9x + 11
---> x = 7
Plug 7 into either 15x - 31 and 9x + 11:
15(7) - 31 = 74 degrees
and
9(7) + 11 = 74 degrees
Add them together, and you get 148 degrees.
Finally, subtract 180 from 148 to get 32 degrees for angle S.
This expression is the difference of two cubes:
x^3 y^3
----- - -------
2^3 3^3
The rule here is a^3 - b^3 = (a - b)(a^2 + ab + b^2), so
x^3 y^3 x^2 x^3y^3 y^2
----- - ------- = (x/2 - y/3)*(-------- + ----------- + --------- )
2^3 3^3 2^2 6^3 3^2
An easy way to solve this equation is to plug in the coordinates.
A. 6(2) + 8 ≠ 1
✅ B. 6(-1) + 8 = 2
C. 6(2) + 8 ≠ 4
D. 6(-2) + 8 ≠ 4
Answer:
B is correct option that helps
