Expression #1: 5(x+2)-7 this equal to 23 Expression #2: 5x-5. this equal to 15
Determine the value of Expression #2 when x-4. Based on your answer, what can you say about the equivalency of these two expressions?

the answer would be 484

step-by-step explanation:

just multiply 0.484 times 1,000 (formula)

i believe that the slope of the line is -5

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)
