Where can we put parentheses in 45 – 22 +9 to make it equivalent to 14? Choose 1 answer.
45 – (22 +9)
(45 – 22) +9

45 – (22 + 9)

Step-by-step explanation:

45 – (22 + 9)  = 45 - 31 = 14

(45 – 22) + 9 = 23 + 9 = 32

45 – (22 + 9)

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)
