((−3r^3)(s^5))2−r^6s^10

=9r^6s10+−r^6s^10

Combine Like Terms:

=9r^6s^10+−r^6s^10

=(9r6s10+−r6s10)

=8r6s10

=8r^6s1^0

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)

27 +27 or 27times 2=54

the diffrence is 0
