Answer:
Yes
Step-by-step explanation:
7 = x
5 = y
5 = X + - 2
5 = X - 2
If X is 7 then
5 = 7-2
5=5
yes

don't write sloppy and I'll be able to answer it
Answer:
My guess is 21
Step-by-step explanation:
I would maybe say a Rhombus. They have two likes of symmetry ^^ Hope this helps!
Given the quadratic function, to get the roots we factorize:
3x²-4x-7=0
3x²+3x-7x-7=0
3x(x+1)-7(x+1)=0
(3x-7)(x+1)=0
thus the roots are
x=-1 or x=3/7
thus the sum of the roots will be:
-1+3/7
=-4/7
