If sin(y°) = cos(x°), which of the following statements is true?

triangles ABC and CDE in which angles B and D are right angles, point E is between points A and C, the measure of angle A is y degrees, the measure of angle E is x degrees, the measure of angle DCE is w degrees, and the measure of angle ECB is z degrees

answer is 8x+24

area of vanessa's patio = length × width

given, length = (3x² + 5x + 10)

width = (x² - 3x - 1)

area of vanessa's patio = (3x² + 5x + 10)(x² - 3x - 1)

= 3x²(x² - 3x - 1) + 5x(x² - 3x - 1) + 10(x² - 3x - 1)

= 3x⁴ - 9x³ - 3x² + 5x³ - 15x² - 5x + 10x² - 30x - 10

= 3x⁴ - 4x³ - 8x² - 35x - 10

hence, expression of vanessa's patio = (3x⁴ - 4x³ - 8x² - 35x - 10)
