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
It will be -5 I pretty sure but I’m not sure
Answer:
Step-by-step explanation: 36-30%= 25.2
your answer should be 25.2
The measure of a straight line is 180
125+30=155
180-155=25
x = 25
