F(x) = -2(x - 3)² + 2
f(x) = -2(x - 3)(x - 3) + 2
f(x) = -2[x(x - 3) - 3(x - 3)] + 2
f(x) = -2[x(x) - x(3) - 3(x) - 3(-3)] + 2
f(x) = -2(x² - 3x - 3x + 9) + 2
f(x) = -2(x² - 6x + 9) + 2
f(x) = -2(x²) - 2(-6x) - 2(9) + 2
f(x) = -2x² + 12x - 18 + 2
f(x) = -2x² + 12x - 16

Maddie's backyard is 25 meters by 25 meters. She wants to put a square cement patio in her backyard. She does not want the patio
luda_lava [24]

The inequality that represents the possible length of the patio is √A < 625.

<h3 /><h3>How to represent an inequality?</h3>

Maddie's backyard is 25 meters by 25 meters.

Therefore,

area of the backyard = 25 × 25  = 625 m²

Hence,

She wants to put a square cement patio in her backyard.

A = area of the patio, in square meters.

Hence,

area of the backyard = 625 m²

Therefore, the inequality that represents the possible length of the patio is √A < 625.

Jordan wrote the following description. Three fewer than one fourth of x is 12. Write an equation to represent the description??
VMariaS [17]

Answer:

1/4x - 3 = 12

Step-by-step explanation:

When it says "three fewer," it means subtract three from one fourth of x. "Is" always means the equal sign. Knowing this, we get the equation:

1/4x - 3 = 12
