Hint: "4x 2 - 25 = 0" is nearly meaningless. You want 4x^2 - 25 = 0.
Note that both 4x^2 and 25 are perfect squares, so this is the difference of two squares, and is equal to (2x-5)(2x+5)= 0.

Option B. ![\$1,224](https://tex.z-dn.net/?f=%5C%241%2C224)
Step-by-step explanation:
step 1
Find the area of the playground
The area of the playground is equal to the area of a rectangle plus the area of a triangle
![A=(10)(36)+\frac{1}{2}(36)(24-10)=612\ ft^{2}](https://tex.z-dn.net/?f=A%3D%2810%29%2836%29%2B%5Cfrac%7B1%7D%7B2%7D%2836%29%2824-10%29%3D612%5C%20ft%5E%7B2%7D)
step 2
Find the number of bags of wood chips needed
by proportion
![\frac{1}{4}=\frac{x}{612} \\ \\x=612/4\\ \\ x=153\ bags](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B4%7D%3D%5Cfrac%7Bx%7D%7B612%7D%20%5C%5C%20%5C%5Cx%3D612%2F4%5C%5C%20%5C%5C%20x%3D153%5C%20bags)
step 3
Find the cost
![\$8.00*(153)=\$1,224](https://tex.z-dn.net/?f=%5C%248.00%2A%28153%29%3D%5C%241%2C224)
Answer: (0, 3)
Step-by-step explanation:
The y-intercept of the line is where the line intercepts the y-axis. In other words, the coordinate value of the line when x is 0.
Well if we're estimating, we know that 9 x 5 = 45 so 90 x 5 = 450
Your answer is B 450
