Just graph is bruv. The app is called desmos
D would be your answer. Since the x is negative the graph is decreasing and -3 is you y-intercept
The answer is the square root of 18 because of Pythagorean theorem
It is 62 degrees because the line is 180 degrees, and angleSPR is 118, so if you subtract 180 and 118, you get 62
X = E/W dimension
<span>y = N/S dimension </span>
<span>4x + 4x + 2y + 2y = 64 </span>
<span>8x + 4y = 64 </span>
<span>4y = 64 - 8x </span>
<span>y = 16 - 2x </span>
<span>Area = xy = x(16 - 2x) = 16x - 2x^2 </span>
<span>Maximum of y = ax^2 + bx + c is when x = -b / 2a </span>
<span>so x = -16 / -4 = 4 </span>
