Left to Right
Step 1: Write expression
7 + (5 - 9)2 + 3(16 - 8)
Step 2: Parenthesis (subtraction)
7 + (-4)2 + 3(8)
Step 3: Parenthesis (multiplication)
7 - 8 + 24
Step 4: Subtract
-1 + 24
Step 5: Add

The equation of the circle is (x - 1)^2 +(y + 9)^2 = 144
<h3>How to determine the circle equation?</h3>
The given parameters are:
Center, (a,b) = (1, -9)
Radius, r = 12
The circle equation is calculated as:
(x - a)^2 + (y- b)^2 = r^2
This gives
(x - 1)^2 +(y + 9)^2 = 12^2
Evaluate the exponent
(x - 1)^2 +(y + 9)^2 = 144
Hence, the equation of the circle is (x - 1)^2 +(y + 9)^2 = 144

Answer:
4
Step-by-step explanation:
We know that oppostie sides of a rectange have to be equal
therefore
18=10+2x
solve for x
8=2x
x=4
