I'm not sure if you're asking for a number in place of Q, but if so then:
Anything between 1 and 2.
12 * 1.5 = 18.
Step-by-step explanation:
Perimeter of figure =

Answer:
(-24y+4+12)
Step-by-step explanation:
You take the (6y-x-3) and individually divide each term by -4.
AB = √(8^2 + 6^2)
AB = √100
AB = 10
AC = √(8^2 + 15^2)
AC = √289
AC = 17
BC = 9
P= AB + AC + BC
P = 10 + 17 + 9
P = 36 units
34)
Area of ABC = 1/2 x 8 x 9
A = 36 square units
