Answer:
W=A/L
Step-by-step explanation:
If the area of the rectangle is L*W, you can just rearrange the equation A=L*W to get W=A/L, an equivalent equation.
Let
in this problem
f(x)=g(x)
so
using a graph tool
the solution is the intersection of both graphs
see the attached figure
the solutions are
x=-1.89
x=2.66
8n^2-3n+10 + -3n^2-6n-7
8n^2 + -3n^2 = 5n^2
-3n + -6n = -9n
10 + -7 = 3
Put them all together and you get 5n^2-9n+3
I tried to space them out so that it makes more sense.
I'm pretty sure that it is 140. Hope I helped!
8p² + 71p - 90
8p² + 80p - 9p - 90
(8p - 9)(p + 10)
