You have received an encoded message: 34, 101, 13, 16, 23, 45, 10, 8, 15, 50, 8, 12. you know that the message
was encoded using matrix =
1 2 3
0 2 1
1 1 1

a. store your message in a matrix c. what are the dimensions of c?

step-by-step explanation:

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)

ask the math teacher she or he would know lol.
