Can someone please solve this before my mom takes my phone?

Find and simplify an expression for the area of five rows of x squares with side lengths of x centimeters.

State how many imaginary and real zeros the function has. f(x) = x3 - 20x2 + 123x - 216

The random variable x has probability density function f (x) = k(−x²+5x−4) 1 ≤ x ≤ 4 or =0 1 show that k = 2/9 find 2 e(x), 3 the mode of x, 4 the cumulative distribution function f(x) for all x. 5 evaluate p(x ≤ 2.5). 6 deduce the value of the median and comment on the shape of the distribution.
