We know that
[area of rectangle]=length*width
area=2g²<span>+34g+140
</span><span>width =2g+14
</span>
step 1
find the roots of 2g²+34g+140
using a graph tool-----> to resolve the second order equation
see the attached figure
the solution is
g=-10
g=-7
so
2g²+34g+140=(2g+14)*(g+10)
therefore
the length is (g+10)
the answer isthe length is (g+10)
7d+12-14d-3
Combine like terms
-7d+9
Hope this helped.
Answer: 72/48 unless you have to simplify which would be 3/2 or do you want decimal?
