The following steps are used to rewrite the polynomial expression (x + 4y+z)(x-7y). Step 1: x(x - 7y) + 4y(x - 7y) + z(x-7y) Step 2: x2 - 7xy + 4yx - 28y2 + zx - 7zy Step 3: x2 - 7xy + 4xy - 28y2 + xz - 7yz Step 4: r? - 3xy - 28y2 + x2 - 7yz dentify the property used in each of the steps:​

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)

the answer is 1 becuz if it were 1.0 that would rip apart the entire so ya. : )
