A rectangular garden has a length that is modeled by the expression 2x - 7 and a width
of 3x2 + 4x.
Whats the perimeter ?

Step-by-step explanation:

6x^3+8x^2-21x^2-28x

for the points! : )

there are many solutions.

step-by-step explanation:

step 1: simplify both sides of the equation.

4x+6=4x^2+10x−4

step 2: subtract 4x^2+10x-4 from both sides.

4x+6−(4x^2+10x−4)=4x^2+10x−4−(4x^2+10x−4)

−4x^2−6x+10=0

step 3: factor left side of equation.

−2(2x+5)(x−1)=0

step 4: set factors equal to 0.

x=-5/2 or x=1
