Answer:
4x^2+10x-2=0
Step-by-step explanation:
So the total area of mirror: 2*3 = 6 ft sq
8-6 = 2 ft sq is the area of the frame
x is the thickness of the frame
so we have (2*x)*2+(3*x)*2+x*x*4= 2
4x+6x+4x^2=2
-> 4x^2+10x-2=0
1) -34 which is very simple
2) 4 2/3
Question 8.
The best answer would be A, two times y divided by 7.
Question 9.
The distributive property. Or A.
Question 10.
5(2+y) would be the answer. So, D.
Hope this helps!
