Answer:

6y² - 20y + 6

Step-by-step explanation:

Use FOIL method

(3y - 1)(y-3) = 3y*y + 3y*(-3) + (-1)*y + (-1)*(-3)

                 = 3y²- 9y - y + 3    {add the like terms}

                = 3y² - 10y + 3

2(3y - 1)(y - 3) = 2 ( 3y² - 10y + 3)

                      = 2*3y² - 2*10y + 2*3

                      = 6y² - 20y + 6

PLS HELP!! this is due today pls help me thank u so much.
riadik2000 [5.3K]

Answer:

23.3

Step-by-step explanation:

Use phyth. Thm.

a^2 + b^2 = c^2

A and B are the side lengths, and C is the hypotenuse. The hypotenuse is across the right angle.

Since you only have one side length and the hypotenuse this what your equation will look like:

30^2 + x^2 = 38^2

900 + x^ = 1444

544 = x^2

x = roughly 23.3
