feet. He wants to increase both the length and width of the deck floor by 2 feet. The wood costs $4.25 per square foot. To the nearest cent, how much will the wood for the new deck floor cost?

602.44

Step-by-step explanation:

13.5 times 10.5 equals 141.75 square feet

then 141.75 times 4.25

understand that i don't know the answers

will someone answer his question

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)
