4. Write the polynomial 2u - 4u^6+ u^3+ 9 in descending order and find the degree

the expected value of the random variable : 0, 1 and 2

step-by-step explanation:

use distributive property on all like terms and change your signs if you have a double negative or if you have positive/negative

i think it is c hope that

step-by-step explanation:

let pq = qr = rs = x, and xz = y and zu = z.

if the horizontal lines are parallel, then corresponding segments are in proportion:

substitute:

therefore 3 = y = z.

xu = y + z → xu = 3 + 3 = 6
