Max is stacking logs at his campground for firewood. After his first load of logs, he has 9 logs on the stack. After his seventh load of logs, he has 51 logs on the stack Use sequence notation to represent the arithmetic function
O an = 51 + 6(n-1)
O an = 9 + 6(n-1)
O an = 51 + 7(n-1)
an = 9 + 7(n-1)

D, 9 + 7(n-1)

Step-by-step explanation: the 9 represents his first trip so it goes as the first number, and 7 is for the 7th trip! I did this question and got it right:)

answer: bearing in mind that a rectangle has a perimeter of length + length + width + width.

step-by-step explanation:

p = perimeter

l = length

x=width

p = 2l + 2x

p = 2(l+x)     < ==== perimeter of the base of the box.

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)
