Answer:
Step-by-step explanation:
this is a difference of two squares.. so you need a changing sign in the two parenthesis ( - ) ( + ) like that form and you'll need two 5 and two 8 each with an x and y sooo B looks pretty good
Answer:
ok first you have a 4 which is 1 tenth then you have 4 evens out of a remaining 9 so multiply one tenth by four ninths so as a decimal it would be 5.3444444
We have that
<span>f(x)=-x+0.5
g(x)=x</span>²+3x-4
f(x)=g(x)------------> -x+0.5=x²+3x-4-------------> x²+3x-4+x-0.5=0
x²+3x-4+x-0.5=0---------------> x²+4x-4.5=0
using a graph tool
see the attached figure
the solution are the points (-4.915,0) and (0.915,0)
