Prove: If point A and B have the coordinate a and b, with b > a, and the midpoint M of AB has coordinate x, then x=(a+b)÷2. Please help i only need the answer to the last two reasons! :)

5   1/4   miles per hour

step-by-step explanation:

15   3/4 / 3 = 5   1/4

the equivalent expression are always the hardest ones but you look at the gcf also

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)

38 was the other number of your question.
