The earth is about 150 million kilometers from the sun. the orbit around the sun is not a perfect circle, but is approximately a circle. if the orbit of the earth around the sun were circular, what would be the equation if the origin of the coordinate system were placed at the sun? x² + y² = (150,000,000)² x² - y² = (150,000,000)² x²y² = (150,000,000)²

step-by-step explanation:

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)

the square root of 16 is 4.

4*4 = 16
