2 points 1) Which system of equations has the same solution as the system shown?
x - 2y = 10
3x + y = 11
(1) 2x + 2y = 10
3x + y = 11
(2) X-y = 5
3x + y = 11
(3) 4x + 4y = 10
3x + y = 11
(4) 2x - 2y = 20
-3x - y = 11

give me time

Step-by-step explanation:

something over 10 so ? /10

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)
