Question 10. explain this in length and tell me the work that comes with it

a = -1.5

b = 3

Explanation:

You can see that there are four even sections between each number that is written on the number line. With this information, you can conclude that each marking represents .25 of the space between the markings. Two spaces represents .50 of the space between the markings, and so on.

For example, .25 of -2 would equal the first marking, which is -1/2. .50 of -2 would equal the second marking, which is -1. Finally, .75 of -2 would equal the third marking, which is -1 1/2.

Keep in mind that the number line goes left on the negatives side and right on the positives side.

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)
