Answer:
If the perimeter of the triangle is 9x + 12 inches, which expression represents the length, in inches, of the third side of the triangle? 6x^2 - x - 12 The length and width of a rectangular park are determined by the polynomials (3x + 4) and (2x - 3).
Step-by-step explanation:
You can solve this question by equating the two linear systems (by "substitution" or "elimination")
By substitution
-Take Equation 2 and substitute it in Equation 1
you will have (b-2) - 3b= 16 => -2b=18 => b=-9
-Then, take b=-9 and substitute it in one of the equations( it doesn't really matter )
For eg substituting in equation 2 yields a=-11
Final ans: C where (a,b) is (-11,-9)
Well, is just their difference, let's first convert the mixed fraction to "improper" and then subtract.
