Let
x---------> the thickness of the frame in feet
At-------> Area of the mirror and the frame in square feet
we know that
------> equation
--------> equation
equate equation and equation
therefore
the answer is the option
The answer is 9
You divide by 1215 by 15 and the answer is 81
Then you find the square root of 81 and the answer is 9
Answer:
x = 10
<u></u>
Step-by-step explanation:
2x - 4 = 16 try to get x on the left side, and the integers on the right

2x = 20
Now, divide by 2 on both sides
2x/2 = 20/2
<u>x = 10</u>
Answer:
y=-1
Step-by-step explanation:
use point slope formula y-y₁=m(x-x₁)
find m which is slope -1--1/-4--1= 0/-3= 0
plug in the equation and use the first point
y--1=0(x--1)
y=-1
