To answer, allow the width of the frame to be represented by x. The dimensions of the frame should then be, 11+2x and 6+2x. Subtracting the area of the inside of the frame from the area of the outside should be able to give us 18 cm². The equation,
(11 + 2x)(6 + 2x) - (11)(6) = 18
The value of x from the equation is equal to 0.5. Thus, the width of the frame should be 0.5 cm.
That can be expressed as, assuming x is the number, 2(x+15).
9/2+5/78
9/2+47/8
83/8
10 3/8
decimal form 10.375.

Answer:
1/4
Step-by-step explanation:
3 red + 6 green = 9 total
P( red) = red/total = 3/9 = 1/3
Now we don't put it back
2 red + 6 green = 8 total
P( green) = green/total = 6/8 = 3/4
P (red, keep,green) = 1/3 * 3/4 = 1/4
Answer:
x=65
Step-by-step explanation:
All triangles angles =180, so you have to add up 56 and 59, to get 115, and then subtract 115 from 180 to find the last angle.
I hope this helps!!!
