Answer:
x=30
(Option 2)
Step-by-step explanation:
Well if the <1+<2=180 then you can put the equation as 4x+10+x+20=180. We can simplify that to be 5x+30=180. Minus 30 from both sides: 5x=150; x=30
Answer:
(7x+5)(7x-5)
Step-by-step explanation:
We can use the difference of squares equation which states that when a number is multiplied like: (ax+b)(ax-b) then it equals (ax-b). In this equation, since there is no "b" in the typical ax^2+bx+c, we can recognize that the answer is not a square, but a difference of squares.

Then, radius =
Area of circle = 
Area of pizza = 
Side of square = 12 inches
Area of square = side x side.
Area of square = 12 x 12 = 144sq. inches.
Area of box empty = Area of square - Area of pizza
= 144-78.5 sq. inches
= 65.5 inches
Hence, 65.5 inches of the box is empty.
