Step-by-step explanation:
9(x - 11) = 9
x - 11 = 9 / 9
x - 11 = 1
x = 1 + 11
x = 12
Hope it will help :)
Answer:
(10x + 8) is the polynomial expression for the perimeter of the blanket.
Step-by-step explanation:
The height and width of the rectangular blanket are (2x - 3) cm and (3x + 7) cm respectively.
Now, the perimeter of a rectangle having height h and width w is given by
P = 2h + 2w
⇒ P = 2(2x - 3) + 2(3x + 7)
⇒ P = 4x - 6 + 6x + 14
⇒ P = 10x + 8.
So, this is the polynomial expression for the perimeter of the blanket. (Answer)
