PLEASE. HELP. ME.

For the graph, what is a reasonable constraint so that the function is at least 600?
A. 0 ≤ x ≤ 20
B. −10 ≤ x ≤ 30
C. x ≥ 0
D. All real numbers

3.how is solving radical equations different than solving linear equations?

step-by-step explanation:

answer: y=0 if that is what u r looking for

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)

answer: answer is b.

[m < b = 120º]
