Help find the answer for a and b worth 10 points

a) 2a + 6(a - 2) = 44

b) short side = 7 cm     long side = 15 cm

Step-by-step explanation:

a)    (2 x a) + [2 x 3(a - 2)] = 44

      2a + 6(a - 2) = 44

b)    2a + 6(a - 2) = 44

       2a + 6a - 12 = 44

           8a -12 = 44

              8a = 56

                a = 7

       Therefore, one side has length of 7 cm, and the other has

       length of 3(7 - 2) = 15 cm.

Hope this helps!

y=−9/2x+10

step-by-step explanation:

let's solve for y.

0−9x−2y=−20

step 1: add 9x to both sides.

−9x−2y+9x=−20+9x

−2y=9x−20

step 2: divide both sides by -2.

−2y

−2

=

9x−20

−2

y=

−9
