Which of the following is a valid conclusion based on the given argument? If 2x + 3 = 13, then x = 5.
a. x -5
b.2x + 3 =/ 13
c. x = 2
d.3x - 5 - 13

5x+2x=49

7x=49

x=7. 35 apples

-4

step-by-step explanation:

do 6-10=

if u need it to be negative.

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)
