Answer this try to and show your work (don't have to if you can't) put a factor back into the square root: a) 7 * √10 b) 6 * √x c) 3 * √ 2a d) 5 * √3 e) 10 * √y f) 5 * √ 3b

a) 7 * √10 = √49 √10 = √490

b) 6 * √x = √36 √x = √(36x)

c) 3 * √ 2a =√9√(2a) = √18a

d) 5 * √3 = √25 √3 = √75

e) 10 * √y = √100 √y = √(100y)

f) 5 * √ 3b = √25 √(3b) = √(75b)

Step-by-step explanation:

q=13

Step-by-step explanation:

(8q-5)°+81°=180° (angles on a str line)

   8q-5+81=180

            8q=180+5-81

                =104

              q=104÷8

                =13
