Answer:
B.2r+6=30
Explanation:
It costs $6 dollars just to get in. Subtract 6 from 30. 30-6=24
Divide 24 by 2. 24 divided by 2 equals 12.
Answer:
The y-intercept of the line is -6.
Step-by-step explanation:
Put 4x-6 into y= on the graphing calculator and the point (3,-6) is in the table.
It is a rational number because it is a terminated decimal and can be expressed as a fraction.
The polynomial that is a perfect square is 16x^2 + 24x +9. Option C shows the polynomial which is a perfect square.
<h3>
What is square?</h3>
The square can be defined as a two-dimensional figure that has 4 equal sides.
Given are the equations of the areas of the polynomial.
Option C: 
We can write the above equation as,


Here a = 4x and b = 3, so

The simplification of the area of a polynomial is (4x+3)^2 which represents the area of a square.
Hence the polynomial that is a perfect square is 16x^2 + 24x +9. Option C shows the polynomial which is a perfect square.
