if ab=3x+11 bc=2x+19 and cd=7x-17 find x
Something is missing; Is it the perimeter?
what is 3x + 11 = 2x + 19 ?
To find the value of x, we can set up an equation by equating two of the expressions involving x. In this case, we can use the fact that ab = bc and bc = cd.
First, let's equate ab and bc:
ab = bc
Since we know that ab = 3x + 11 and bc = 2x + 19, we can substitute these expressions into the equation:
3x + 11 = 2x + 19
Now, let's solve this equation:
3x - 2x = 19 - 11
x = 8
So, x is equal to 8.
