1. **Problem statement:** Given the function $f(x) = \frac{n(x)}{d(x)}$ where $f$ touches but does not cross the x-axis at $x = -2$, and the function $g(x) = \frac{ax^3 + bx^2 + 6}

1. **State the problem:** We need to draw the graph of the function $y = x^2 - 4$. 2. **Formula and explanation:** The function is a quadratic function of the form $y = ax^2 + bx +

1. **Stating the problem:** Given that $a - b = b - c = 2$, find the value of $$\frac{(a - b)^2 + (b - c)^2}{(a - c)^2}$$. 2. **Understanding the given information:** We know both

1. **State the problem:** Factorize the expression $$120c^2 y^3 - 8c y^2$$. 2. **Identify the greatest common factor (GCF):** Look for the largest factor common to both terms.

1. **State the problem:** Solve the equation $2x + kx = m$ for $x$. 2. **Combine like terms:** Since both terms on the left contain $x$, factor it out:

1. **State the problem:** Evaluate $\log_9 3$. 2. **Recall the definition of logarithm:** $\log_a b = c$ means $a^c = b$.

1. **State the problem:** Simplify the expression $$\log_a(8) + \frac{4}{5} \log_a(14) - \frac{4}{5} \log_a(7) + \log_a\left(\left(\frac{1}{2}\right)^{\frac{9}{5}}\right)$$ using p

1. The problem asks for the mass of 3 servings. 2. To find the total mass, we need to know the mass of one serving.

1. The problem states that Mike has a can of potato chips with 16 chips per serving and each serving has a mass of 28 grams. 2. To find the mass of one chip, we use the formula for

1. **State the problem:** We have the equation $$W = 15T + 500$$ where $W$ is the amount of water in the pond (liters) and $T$ is the number of minutes water has been added. 2. **I
