Answer: y=14
Step-by-step explanation:
A. 16x11 = 176 + 30x8.75 = 262.5. 176+262.5 = 438.5. Not 470
B. 20x11 = 220 + 26x8.75 = 227.5. 220+227.5 = 448. Not 470
C. 30x11 = 330 + 16x8.75 = 140. 330+140 = 470. C. is the correct answer
D. 31x11 = 341 + 15x8.75 = 131.25. 341+131.25 = 472.25 Not 470
Use distribution to find the answer to this one.
5x * 6x² = 30x^3
5x * 3x = 15x²
5x * 7 = 35x
-1 * 6x² = -6x²
-1 * 3x = -3x
-1 * 7 = -7
30x^3 + 15x² + 35x - 6x² - 3x - 7 → simplify this using like terms (look at the exponent of x and if there even is one)
30x^3 stays becuase there is no other like terms
15x² - 6x² = 9x² becuase they are like terms
35x - 3x = 32x because they are like terms
-7 stays because ther is no other like terms
Put these together in the final answer: 30x^3 + 9x² + 32x - 7
Hope this helps!

Answer:
x = 130°
Step-by-step explanation:
At the points of Tangency, A and B, the angle formed are equal to 90° based on the tangent theorem.
Therefore, m<A and m<B both have a degree measure of 90° each.
Thus, the sum of the interior angles of quadrilateral AOBC = 360° (sum of interior angles of a quadrilateral).
Therefore:
x + m<A + m<B + m<C = 360°
x + 90 + 90 + 50 = 360 (substitution)
x + 230 = 360
x = 360 - 230 (subtraction property of equality)
x = 130°
